Communication with the host was excellent and she tried to help as much as possible but unfortunately our stay was not a good experience. In a nutshell, we couldn't sleep because of the hot temperature in the room and the noise produced by the ventilation. She tried to get the temperature lowered but I guess there's only so much you can do on an old system, especially when the control is in a room that is not accessible to the guests.
In the end, we checked out one day earlier and went to a hotel. It's hard to not sleep 3 nights in a row.
