OP, have you actually stayed in the Air bnb yet?
My last Airbnb experience was weird. I booked a two night stay. Within an hour the host contacted me via email to say she had already booked the place for the same time and she was going to have to cancel me.
I was good-natured about it because it didn’t matter that much to me, I was not invested in this reservation. I told her sure, no problem. Please refund me the money. I don’t have time or inclination to figure out how to do that on your Air bnb system, so please see that I am reimbursed.
I figured it was her responsibility to make the refund happen because it was her error in allowing a double booking.
Well, that was a process. It took multiple email messages, waiting weeks for partial refunds, and then finally a check from the host. My guess is that the host was out of pocket for the Air bnb fee for my own reservation, but that is not my problem.
Even tho it took a few tries, My impression throughout the transaction was the host was well intentioned and honorable. I did once threaten once to go to Air bnb if we couldnt get this refund wrapped ip in a timely way. It eas not necessary in the end.
