Yup...that's pretty damn impressive. 6800 is more than I would personally want to spend, but if you can afford it, why not?
Interesting about the girls thoughts on it.  I wonder what their reaction would be if they knew the actual cost!

I agree. Great staff, great location. This is the hotel I booked into while my collegue stayed at On 8. Have stayed there a few times. They know me now and really helpful.
Not a long walk from CIB!.
As you say, the beds are hard. Have just booked the Grand Suite for August, but the beds nearly turned me off.
One feature that is good there is the outside eating area with seating facing the road, Great for lb watching. I picked up one from that seating!!!.
I checked out other hotels in the area but could not find anything to match the location, value etc. $75.00 AUD  a night. That is about my max budget when lb chasing. Can't see the point in paying more. Have not had complaints from the girls. Sorry I did. When my flight time got stuffed up I had to return to the hotel for the night. Just got an elcheapo room.
When I arrived back from CIB, with the girl, (starts with L and ends with y), said "oh it only has single beds". Funnily enough it did not matter a few minutes later!!. God she was good!.

Thanks PB...more options are always good to have.
I enjoyed coffee at Kinaree several mornings.  A cheap and decent diner type place

Apparently nr 1 and 2 weren't fit for this life after all 

Dynasty Inn,
5 4 Sukhumvit Road Soi 4 Nanatai Klongtoey, Bangkok, Thailand, Bangkok 10110
I was at the Dynasty Inn hotel 3 nights at the beginning of August 2019.
I didn't find any review about this hotel which seems little discussed in this forum, contrary to the Dynasty Grande.
 Why you (and I) would choose this unassuming little hotel (around 60 rooms)? To be in the heart of the action. At your right, count 60 meters to Nana Plaza via Hillary 4 and the Stumble Inn. If you take on your left, Hillary 2 is at 30 meters.
The reviews are good (8.3 on Booking) and this hotel is of course guest-friendly. 
I asked for a non-smoking room at the back of the hotel (quiet rooms). 1 680 baht a night for 2 people. I didn't take the breakfast.
At the entrance of the hotel, the front bar gives you a look at the scene. Very useful to give a rendez-vous to a lb, take a drink and evaluate the chemistry. At night a few ladyboys stand on the sidewalk.
Food from the restaurant is known to be good. I didn't test it.
At the front desk, the hotel staff is friendly and helpful. It's a big plus. The people make the place. No walk of shame. Your guest will let its ID at the reception.
At the check-in they ask for a 500 baht cash deposit for the key.
The back annexe seems to face the rear of Nana Plaza but in the room there is no noise of music or whatever.
The room is quite new, clean and large. 26 square meters. 
Aircon works well, a bit noisy. Comfortable big bed, safe (laptop friendly), fridge, ... Fast wifi.
Complimentary water, coffee.
Bathroom is modern and clean with a hand hose.
All lbs of Nana Plaza know the hotel and will be happy to make the short walk for a session. So no short-time room to pay.
 
All in all I was positively surprised by the quality of this 3 star hotel, clean nice room, friendly staff, located in the heart of the action. I was pleased all the time I spent in that room, feeling well.
Recommend strongly.
Note: Dynasty Grande, on Soi 6, belongs to the same owner and has pool and gym. Around 300/350 baht more expensive by night. Same kind of rooms. Better lobby, front desk not so friendly.

You now have 23 likes Oliver, but I gave my like not for the well worded post, but for all the pics of your beautiful dining companions!
I agree with the advice the BM's have given here.  I stayed at the Mercure (thank you for this review Bwana) and on my first night I ran into the bellboy who helped me with my luggage when I arrived.  He asked me "Where do you go tonight sir?" and I responded "Cindy's Secrets" which got me a big smile and thumbs up from him.
I enjoyed chatting with the girls from reception when they were not with guests...especially Beem and Cherry...they are real sweethearts.  They would tease me about my carousing...not because I was bringing back ladyboys, but just good natured banter in general.
I never got any dirty looks from the other guests or the staff there bringing back girls.  Quite the opposite...the staff were always very polite and respectful towards my companions and the other guests were usually jealous, haha.

Just spent 8 nights at the Mercure on Soi 11 and thought I'd offer up my take.
I had a King room with shower and bathtub, one of several options. It's not their largest or their smallest room, but was plenty large for my needs (photos below).
I arrived at midnight, and check-in was quick and simple. I purchased a room without the breakfast add-on, as I like to explore various breakfast options around town. I booked well in advance, while prices were still depressed by Covid, so got a rate of about $86/night. When I checked in, the rate being offered at that time was about $112.
My room was on the 16th floor and away from Soi 11, so as quiet as a room will get in that part of town. I had no issues with noise
A funny moment: I was only interested in sleeping after a 27 hour trip with a 15 hour time change, but could not figure out how to turn off the room lights. I searched everywhere (I thought) for the switches, finally calling the front desk to send someone up. The control for the room lights (nearly all of them) was in the middle of the bed headboard, hiding behind a stack of pillows.
Description of room:
The room was plenty spacious, and had pretty much everything I would want. The king bed was comfortable and the bed linens were high quality. Four large pillows. There was a desk with two chairs, and an additional two guest chairs with a small table. Opposite the bed there was a small storage unit with two drawers for clothes, and a flat screen TV above it. TV worked fine and was decent sized, but I never watched any TV. To the left of this, towards the door to the room and the door to the bathroom, was a platform to set luggage on, a small fridge (not a minibar), and then a closet with a decent sized safe (big enough for a laptop). Across from the closet was the door to the bathroom. As mentioned, the bathroom had both a glass-enclosed shower, with adjustable/handheld shower head and a rainfall shower head. Across from the shower was a full tub with an adjustable/handheld shower head (for some reason, many Thai girls seem to prefer to shower in the tub...I don't get it). Tub had a wall mounted soap dispenser, shower had wall mounted soap, shampoo, and conditioner dispensers. Next to the shower was a toilet with the essential bum gun, and next to it a shower and sink with ample room for storage of toiletries.
Pros: 
Comfortable bed Good AC that was easy to control air speed and room temp Great hot water. It was easy to control, and never ran low. Two large bath sheets and two smaller bath towels Plenty of seating for guests. Chairs came in handy for sex as well. Housekeeping was responsive to requests for extra towels, hangers, etc. I tipped daily. Good reading lights by the bed. Cons:
Lighting was hard to control. No dimming, and ceiling lights were either all on or all off. No power outlets next to the bed! Charging phones had to be done at the desk or on top of the fridge. This was a nuisance. Aside from liquid soap, shampoo, conditioner and body lotion, there were no other amenities in the bathroom. No plastic hair cover for the girls, etc. Fridge was on the small side. Room for a few drinks and not much else. The Hotel:
The lobby is nothing fancy. From the driveway you walk through sliding glass doors, across a seating area with a concierge stand, past the elevators (one left, one right), and to the actual reception desks. One of the two hotel restaurants (Lily Fu's) is on the ground floor to the right of the hotel entrance, and can be entered from inside or outside the hotel. Another restaurant (Gaucho Argentinean Steakhouse) is loosely affiliated with the hotel and is just to the left of the hotel.
The hotel has a parking garage (4 levels), a pool, bar, and gym that sit above the parking garage, and 16 floors of rooms (1-16, minus 13th, plus a Penthouse level). I spent a fair amount of time at the pool. One of the better pools I've used. There are actually two pools: a smaller and very shallow splash pool for kids and a larger pool, still fairly shallow (1.2 meters) for swimming. The pool is surround by ample seating of various sorts with shade for the sun-averse. The bar sits at one end of the pool, and has a decent drink and food menu. Neither cheap nor overpriced. The gym, glass enclosed and looking out over the pool, was also very good, with plenty of cardio and weight machines.
Pros:
Lobby easy to negotiate. It's a decent walk (of shame?) to the elevators, but you have the option of skipping the desk and taking your guests straight to your room. Elevators require a room key to get to a particular floor, so no surprise guests will appear at your door (as has happened to me at other hotels). Breakfast buffet at Lily Fu's is excellent, at 299 baht. Egg station, all the usual options for American/English breakfast, tons of Asian options, good selection of fruit, juices, breads and pastries, coffees and teas, etc. One can sit open air in the front of the restaurant facing Soi 11 or sit back further inside or at the bar. In the evening, Lily Fu's is a bar/restaurant and is pretty active. Good drink options, reasonably priced, and usually quite crowded. The food is primarily pan-Asian and good, but there are better options, so I only had a quick meal there one time when convenience was key. Gym was great and never crowded. Pool would get busy, but there was always ample seating. Cons:
The hotel is definitely a family hotel. Not exclusively so, but if you're a shy monger just know that you'll be dealing with lots of couples on vacation, families with kids, and so forth. The clients were incredibly diverse, a little United Nations. Didn't bother me at all, but I know some here prefer hotels that cater primarily to mongers. I'm afraid there are fewer and fewer of those, and they are generally not the best hotels. Pool area could get noisy when a few families with kids would show up. The pool is my reading area, and shouting kids are distracting. Come on the early side for breakfast. At least while I was in town the restaurant got quite crowded by 9:30. Fortunately, I'm an early riser. Conclusion:
Depending on the rate I can get, I'd definitely stay again. Did I mention that Cindy's Secrets is about 100 yards from the hotel, and that it's a short walk to Check In Bar? And that Soi 11 really has lots of options for food at any time of day, and plenty of nightlife. By 9 pm freelancers show up along Soi 11 closer to Sukhumvit. I definitely preferred staying here over Soi 4. Soi 11 is now also the hub for the mobile marijuana dispensaries. There were at least ten vans selling marijuana along Soi 11 (and tons of dispensaries along Sukhumvit), including two vans parked in front of the Mercure in the evenings. Didn't imbibe. I liked getting in walks to the skytrain from the hotel (maybe 5 minutes), and Terminal 21 is just a 10 minute walk.
The morning I left, at 5 am, there were four girls from Cindy's sitting in front of my hotel, so I went out and chatted with them. The street was still pretty active, but mostly filled with bargirls and freelancers ending their nights by getting something to eat or drink. I don't think Soi 11 ever sleeps.
 

Thanks. I’ll do that next time

When I landed early afternoon last Friday the arrivals area was extremely busy. I didn’t have too much of a difficulty navigating things though. My only issue was that I didn’t change any money near the baggage claim. A. It was too busy and B. I thought I read that there were better rates on the lower level. But once I got to the taxi level I couldn’t find any exchanges and my bank card didn’t work in the ATMs. Luckily I had enough THB in my pocket from last trip to pay the taxi

Thanks for taking the time to answer those questions.  Really appreciate it.

1. I don't recall, but think something essential was wired to that plug near the bed.
2. I took a couple of freelancers to the desk and had them leave their IDs, then after the deed was done walked them back to the reception desk to get their ID. I took a few Cindy's/CIB girls upstairs without dropping off IDs because there's a certain guarantee of safety when the girls work for Cindy or June.

Thanks very much for the review.  This helps me a lot as this is certainly the most in depth review I've found on this hotel including reviews from travel sites, the Accor website, etc.
You did good on the price as I'm booked there for my first 5 days in late Feb in a "Deluxe King" room and the rate I got was 22K Baht. ($134 USD per night all taxes in)  My booking is no money down, free cancellation and breakfast for 2 included.   I had a cheaper reservation but had to cancel it as my trip got delayed and it appears that around March is quite busy for tourism and all hotels that I've looked at are quite expensive from late Feb to late April.
No outlet by the bed is a big con for me as I have a CPAP machine...I've needed it even when I was young and fit and now that I'm old and fat I absolutely cannot sleep without it.  Maybe I'll bring an extension cord (or have hotel provide one), but in your picture of the bed it almost looks like there is a power outlet to the right of the bedside table right near the floor?
Love that it is walking distance to many lb bars...that was certainly a factor in me choosing it.  You mentioned you could skip the desk and bring guests straight to your room...if you went to the counter would the doormen check visitors ID and check with you when your guest left to make sure everything was okay?  This sounds like it wouldn't be a bad idea if I had a freelance guest, but would probably skip this step if I brought back a well known girl from Cindys or CIB or whatever.  Thoughts?
