I rate Hyatt Regency, not as the best hotel but the best location (for mongers), on corner of Soi 13 Sukhumvit. Price around 7000 THB per night depending on season. I have seen it cheaper but 7K seems to be the average. Suites go for 13,000 THB per night. Great buffet breakfast, nice swimming pool and gym on level 6 and very cool rooftop bar. I have stayed at Park Hyatt (over 16,000Thb per night for standard room) which was very nice but not the same awesome location as Hyatt Regency.
Hyatt Regency is a very nice 5 star hotel. 1 minutes walk to Soi 11 with heaps of restaurants to choose from, and Cindy's Secret.
450 meters - 4 minutes walk to Check-in Bar. 8 minutes walk to Nana Entertainment Plaza, 9 minutes walk to Soi Cowboy. 2 minutes walk to Nana BTS if you want to venture out around Bangkok.
Street walkers (GG and LB) right out the front most nights.
When I stay there I very rarely venture further than 450 meters!
Or Sofitel, just on next block past Soi 13. I have not stayed there but still great location.
