I had the same bad experience and the last time was a disaster. I have 3 listings for 3 different private rooms in the same location. So the guests share bathroom, living room, kitchen...
One day someone booked a room for the same day for 1 person, the other bedrooms were booked for a single and a family of 3. At some point, we realized the guest brought 4 friends, two were sleeping in the sofa, other two in the booked room and another one in someone else's bedroom. I called them and explained the situation, we don't have space for that many ppl in one room, that would disturb other guests and we have extra fees for extra guests($10). The person who reserved the room said he made a mistake and thought he was renting the whole house, which even if that was the case he never mentioned 5 ppl, not even when he checked in.
In short, during their stay they broke glasses, clogged twice the bedroom and left the common areas a mess. It's been 2 weeks since I claimed $50 through the resolution center (which we agreed) and so far not even that I received for the 2 nights they stayed. I was left with no review from them of course, another guest preferred not complete the review and the family gave 4 star.
