This place is located near Teenee Korat, Bule Saloon or Robert's restaurant. They opened around 2008 and it's a perfect place to get a nice room for 600 baht to 900 baht. The location is quite nice, in the old town.

Their website has many pictures should you be interested to have a look. It's not in English but you will easily understand. More pictures than words...
