Host was responsive to questions and concerns. If you plan to use the in-wall air conditioner, consider checking for black particles on the vents, as well as behind the vents. We left ours off because they looked like mold. The host didn’t think it was an issue for them to thoroughly clean it, although photos were provided. The host was nice enough to offer us a regular fan. We just left the windows open. However, it was very warm in the room even though we are next to the beach.
