@Branka-and-Silvia0 I was not available when the guests arrived so I asked my wife to meet him. She asked him for ID simultaneously to the keys. He took the keys and claimed that he didn't have any ID on him, so she told him to make sure to have some later in the evening when I'd be back.
By the time I arrived (a few hours later) he had sent a message saying that he was cancelling the reservation because my "rules are kinda strict i rather cancel then have a bad time or trouble with rules it will not work".
A few hours later I received an AirBnB message informing me of the cancellation while claiming that I'd be given the first night's rent plus the cleaning fees. But then, some 25 hours after that, I received a new AirBnB message saying that they (AirBnB) had decided "to fully refund our guest" because "Our hosting standards are a set of guidelines to ensure guests have a positive and consistent travel experience with each Airbnb reservation".
I've never had a reservation cancelled before (I've been very fortunate to have mostly good guests) and I'll admit to being very surprised that AirBnB can decide to reimburse a guest (who is likely "a bad apple") instead of adhering to the cancellation policy. The reservation was made 48 hours before check, and I'm wondering if it's possible that the credit card was stolen?
