Very good location, just right at the bottom of BTS Phaya Thai which is also the exchange station to airport railway. 7-11 is just downstairs. Let's Relax and another more local one are within 5 min walking distance if you wanna do massaging. Basically clean. Towel is provided. I stayed in single room which is very very very small and dark. Just to remind that the door of this room type is just like the photo shown. And the room is just next to the bed only , that means you are actually in the same room of dormitory. No mirror inside. You could hear everything happened around your room, sad for you if you have inconsiderate room mates. I don't prefer the design of the way you put the luggage under the bed as it is inconvenient in the room, no space to open it, and makes noise.
The pool on rooftop is very very small, it's like the pool for sauna. The common area is quite spacious, you can have free drink and snacks all the day. Kitchen is clean and the lady staff there is very nice, keeping the common room clean and tidy. Breakfast is simple but good enough! They got elevator inside building except from ground floor to reception. Sometimes at night it's cold with the air con, you can't adjust it.
