This is literally the closest place you can live to Tiger Muay Thai without staying in their onsite quarters. If you threw a paper plane from the hotel window, it would be close enough to land inside Tiger, right across the street.
Rooms are spacious but very basic, nothing near luxurious, which reflects in the price, my room was around USD 40/night in December (busy season). Only amenities with the room are two bottles of complimentary water, and the wall soap/shampoo dispensers in the standing shower. All rooms are air-conditioned.
In terms of facilities, they have a small pool where guests use for tanning poolside rather than swim in; there is also a laundry room where it costs 40baht to use the washing machine and 60 baht for the dryer. Most rooms have a balcony with a drying rack as well.
