We liked our stay at the Arenal Montechiari Hotel. It was different from a usual hotel because of the small, individual houses.
Positive things about the houses are ...they have air conditioning, are clean, have a room safe for valuables, have a TV, and the breakfast is adequate. Every unit has a small porch with two chairs on it. The price for staying there is very reasonable, and the grounds are pretty with flowers. The staff was friendly and helpful.
Negative things are... the small houses are very rustic. You can see light between the boards on the door and there was a gap under the door. Despite that, we did not see any insects in the unit. Our house had two beds that were tightly squeezed into the room. There wasn't a chair for lounging. The small houses are very close together and conversations can be heard from people outside.
