We spent two nights at Baan Sukhumvit's Soi 20 location in mid-December 2010. We stayed in a very nice room on the third floor with a king sized bed and large, clean bathroom. The staff were incredibly accomodating. They provided logistical advice and stored two of our bags for ten days while we visited other portions of Thailand. They also moved our bags to their Soi 18 location, where we had a room booked upon our return to Bangkok.
There are many good places to eat within easy walking distance of the hotel, as well as being not too far from the crazy world that is Soi Cowboy. Also very close to the subway and Skytrain.
We would stay there again in a heartbeat.More
