The question of reasonableness cuts both ways: the high cost for the Airbnb unit plus the added fees including the cleaning ones, and the lists of guest to-do items upon check-out. The two combine and quick it becomes the feeling that you're paying a lot more than a hotel and yet have a lot more servicing to do yourself. If there is a very high cleaning fee, it becomes increasingly unreasonable to ask a lot of your guests to spend time cleaning everything before they leave.
