there are 2 major problems with this hotel. You can get a room with a nice almost noiseless aircon or a room with the one you will not use because most of its energy goes into sound production.
Also when you pay with you credit card make sure they charge you in thai baht, or they automatically convert the payment sum into your cards currency by the rate wich is far from fair.
So check the room first for the aircon condition.
there is no swimming pool or gym.
