Unit was very clean and comfortable. The downstairs area was always comfortable, however the upstairs bedrooms get pretty warm. The ac controller has instructions not to put the air any lower than 72 or risk being charged/responsible for "any damage" lowering the ac may cause. The minimum tempature of 72 keeps the downstairs areas plenty cool, but the upstairs bedrooms not so much. As someone who does not sleep well in warm environments, i had difficulty sleeping while there, and ended up visisting walmart to purchase a small fan. It may not be an issue during other times of the year, but in the middle of summer, it makes it uncomfortable. Ceiling fans in the rooms would help, but really the minimum temp os 72 is excessive. Only other suggestion would be to make it very clear to potential guests to bring their own towels.
