We stayed at the Midas Resort in one of the spare rooms which shares a bathroom with another room and resides at the back of the building. Excellent air condition, the mattress was good. Both the spare room and the shower were kept clean OK. You will get the chance to buy breakfast there as well, maybe a little overpriced. The rest of the hotel installations , pool and so on, looked nice but we didn't really use them. To downtown San Ignacio it's probably a 10 min. walk.
Hint: The pictures of the room are not showing the spare room.
