I had to cancel the reservation because it was a very hot day and the unit didn't have a/c. I don't necessarily blame the host because a/c was not in the list of amenities. It was just unbearably hot inside the room on that day. The host was actually very nice about cancellation.
One thing I need to add is that communication was difficult because the hosts didn't speak English at all. We communicated with google translators most of the time.
