So pretty much this has never happened to me. I personally made sure everything is right for the guest.
suddenly the guest arrives to the apartment and says he does not like it and I asked him if they need anything extra. they said yeah and I said that I will get home and bring it to them(nobody asked for that before)
Suddenly they say to me that they say to me they are leaving for a hotel and left after 30min of check in.
I have strict cancellation policies and I have pictures of everything as described and clean.
what do I do in this situation? will they call airbnb? will I get paid for those nights? I have not even met them they left.
