Well, I bought some glue and I glued it back in. I didn't have to do that, if I have real problems Airbnb has always refunded me, and hosts have always been great... But i didn't mind.
Was your trip in USA? I get a weird kind of feeling that Airbnb is awful in the states... But I'm not sure that's an Airbnb problem specifically. I feel like in the states it's a business, where the rest of the world is more easy going?
