We had a lovely stay at Sonia’s. The a/c vented with a large hose, which we had to shut in the sliding door, so not very efficient, but kept cool enough. The one in the bedroom made a loud banging noise like it was out of balance so we didn’t get to use it in a heat wave. Also the dryer vented into the bathroom, so it heated things up. All not a problem when it isn’t 93 degrees outside! Otherwise everything was wonderful.
