Two times a year I fly to asia. Then I have stop over in BKK. My recommandet place for gay people is the Babylon. Babylon is the biggest gay saune in asia, located in a quiet area next to Sathorn, not far from Silom road with the nost popular gay bars and clubs.. The Babylon complex has a hotel with a large number of rooms. In the main building you find the cheaper and simple but clean rooms. Appart from the penthouse rooms they don't have own bathroom, but there are bathrooms for all visitors on any floor.
I prefer the comfortable ant quiet Bulgari Garden Suites behind the main building. They have nice rooms, own bathroom and separate gardens to share with 2 or 3 other guests.
For compemantary breakfast you have to go into the main building.
The stuff is very friendly will help you for your trips in other areas in thailand.More
