The rooms require AC in the dry season
We booked a double bedroom with no AC for $8/night with a nice private bathroom.
The pro is the price.
The con is that no AC in their room during the dry season is a bad idea. The room have windows that do not open. The heat goes up and up and, by night, the room temperature reached over 40'C. We didn't really sleep. Eventually, as each room as AC available for extra $, we took it and the room became recommendable.
Also, don't hesitate to change room if the one you have smells. The one they gave us first had an awful smell (seriously, it was bad), we asked to change, no problem, the second room was fine.
