I'll preface this by saying that we stayed there at the end of July when there was a heat wave going on. In non-heat wave times, you are likely to be fine.
When we checked-in at 7pm, the temperature inside was 83 degrees. We went into town to allow the house to cool off, and got back at 11pm where the indoor temperature was still 80 degrees. It was still 80 degrees inside at midnight which made it very difficult to sleep. We contacted the host who said that he could bring over a portable A/C unit next evening.
Having paid $700+ for a 2-day rental where we can't really use the house most of the time and had a very difficult time sleeping the first night, I asked whether we can just leave and get a refund for the second day. I was told that since I had chosen the no-refund option, that it was not possible.
I'm pretty used to booking hotels with a non-refund option where if my travel plans changed, in those cases, I just ate the cost. However, we the disagreement was about the usability of the house. If this was a hotel or even if it was just a host renting out his house, it would be been resolved most likely. However, this is an AirBnB business where although the host has a nice story as a facade on the Airbnb site, I wasn't dealing with that person. I was dealing with a property manager who was managing 25 other Airbnb rentals, and his primary concern is getting his money and less on working with people who stayed there.
In the absence of a heat wave, I'm fairly sure none of these issues would have come up, and everything would have been fine. The house is nice and the neighborhood is nice. But there was a heat wave and the property manager failed to make proper accommodations. Even that is understandable, but if accommodations can't be made in a timely way, couldn't be flexible enough to work with the guest.
