Not sure how to rate this place, basically it's a fantastic location right in the middle if Koh San Road.
Completely basic accommodation, but I paid 600 baht for a twin room, air con, bathroom with free wi-fi.
You can choose cheaper rooms without a bathroom, single beds, cold water only etc.
It worked out at £10 or £5 per night sharing with a friend. What else could you expect for that price??
