I stayed at catys' place for one night. It was really really warm in the room even though you had the choice between closing the door or using a curtain to let some air in. There's no window in the room, as visible on the pictures. The fan in the room helps with the heat but is really loud so you can't leave it running during the nighttimes.
All in all it was all fine, but I wouldn't recommend it for longer stays. Thank you anyways, Caty! 😊
