Stayed here for 3 weeks while sorting out some administration issues for a course I am doing. Although it is a guest house for Indian men, (not sure what they all did?) it makes an adequate base for those wanting to explore BKK and be in a real Thai neighborhood. As a male solo traveler I felt safe and although there were all sorts of bizarre comings and goings (large screen TVs delivered in the lobby etc.), the place wasn't that bad. For 600BHT (18USD) a night you get a very worn old room with dirty windows, but you have a Thai style bathroom which was old but fine for those used to Asian style amenities. Towels and soap are changed whenever you like, and the room is cleaned whenever you ask the lady to do it. She may not give you a smile, but she do clean to a good standard.
This type of room is best suited to a hardy (male) traveler who wants to be away from Khao San Rd etc. but close to the city. I could walk to most places in Surawong and Silom, and there were two great cheap local places to eat nearby. One was Indian, one Thai Muslim. Also a lot of street food in the alleys surrounding the Soi.
Although the bed was hard and it was difficult to get comfortable, the place was very quiet at night and there was very little noise after 10pm. It is close to the British club and Neilson Hayes library, so you can get an excellent full English breakfast, a coffee and get a book out to read as well.
Overall, if you are travelling and just want to be tucked away in a little alley on your own saving money or looking for a job etc. this would suit you well. If you are not a seasoned traveller and you are just being cheap, don't bother, you won't like it. You will not see any other farang living here!
Tip: use the water machines the locals use to refill yr bottles. 1bht-1.5 liters.
