Jeeze that place is right on top of CIB. And Pray Raya, a great Thai restaurant, is also close by. I may rebook.
Though I wonder if that is almost too close. Will the girls be tempted to skeedadle from my hotel as soon as we do the deed being so close to the bar?

This last trip I stayed at Galleria 10 which was pretty good.  No more than your 4 stars worth, but certainly no less!  As a side benefit Its' barely a stones throw from CIB.  I was happy with it. Good value for money.
I also stayed at Night Hotel for the 2nd part of my trip.  Night Hotel used to be Dream and I had fond memories of it, but t's a shadow of it's former self.  Now the hotel is made up of 2 buildings on opposite sides of the road from each other. The better rooms (allegedly) are in Building 2 (the old Dream hotel).   That's where I stayed, though I was given a viewing of the rooms in Building 1, they were okay but felt a bit clinical.
 I don't know if they think they look cool but now the staff all wear black T-Shirts.  They look more like bouncers in a night club than reception staff!  And on the odd occasion they had that kind of "security" attitude as opposed to "welcoming and helpful.  I wouldn't stay there again and  I wouldn't recommend the place either.

I'll be interested in your review. Soi 11 is a great location. There's plenty of excellent food on Soi 11, a lively freelancer scene at night, and--depending on your mood--you're steps away from the LBs and Cindy's and the GGs at Lusty Lady. That's why Mercure has become my BKK base.

I am a cheapo when it comes to hotels and I am perfectly happy at a place like Citrus. My only complaint is that it is a bit of a hoof from there to Sukhumvit and the walk along Soi 13 is a bit boring (though there are some good places to eat like the German Beer House there). 
So I am giving Eleven a try for the first time this trip as I can literally stumble out of bed and be at CIndy's on some of the other interesting places on Soi 11. 

When I was in Bangkok back in July, I visited Soi Thaniya in Silom, which is only 300 meters down from Patpong Road. Amazing how many times I had been to Patpong but didn't know about this place they refer to as 'Little Tokyo' or 'Little Japan' due to the entire street being lined with awesome Japanese restaurants, from Japanese BBQ, sushi, ramen shops and plenty of others. An entrance to BTS SkyTrain Sala Daeng station is just on the corner of Soi Thaniya.
I just visited during the day for lunch but heard it is lit up like the streets of Tokyo at night. I just had a ramen noodle soup at a restaurant called Uchidaya Ramen. 270 baht for their Kyushu Tonkotsu 'Special' ramen. Best ramen I have ever eaten!
If you love Japanese food then put this on your list of places to visit in Bangkok. Go there for dinner, then head down to Patpong to pick up your dessert.
They do have some girlie bars here, located in the top floors above the restaurants at street level. I heard they are very much like the 'hostess bars in Tokyo'. These places cater to Japanese business men. I heard like in Japan, they pay a fee for a girl to sit with them and laugh at their jokes, tell them how wonderful they are and pour their drinks. I been to a few hostess bars in Tokyo and never saw the point of them as you can't bar fine the girls there in Tokyo but I believe you can bar fine the ones in Bangkok but at ridiculous Japanese prices, something like 5000 - 6000 Baht. Screw that! Get down to Patpong to pick up what you fancy for the night, GG or LB at proper Bangkok prices.
Definitely worth a visit if you love Japanese food.
