Yeah I'm not sure what the right answer is here, in terms of how reviews could be structured. Buyers (the people staying at the AirBnB) can really screw things up. Then again, they can screw things up, but it can be the hosts fault. For instance, a poorly attached (suction cup) toiletries holder can fall in a shower, and break a tile (ask me how I know).

Technically the buyer, the person staying there, cause the problem. But it shouldn't have been attached so insecurely that it can fall down.

Hotels have years of experience in making things more bulletproof, and hard to damage. AirBnB is much newer and some of them have a lot to learn.
