So I stayed here last month.
Pros: room quite big, bed is very soft (for those of you who like soft beds this is better than St Regis Grand Hyatt and Hyatt Regency).
Extremely well located if you prefer Soi Cowboy or Thermae and not far from Nana either.
Gym is big, nice sauna too.
Hanging around the pool during the day is excellent.
Cons: bathroom very tired, blue ceramic wall tiles are mouldy (but was obviously too expensive to replace on their recent very limited refurbishment).
On balance (and for the same price) I would stay at St Regis or Hyatt Regency.
They have a cigar lounge and a bar downstairs where you can supposedly pick up quality freelancers but it was dead when I checked it out.
