I believe this is a scam.
Booked the listing and was informed his last guest had Covid 30 minutes after booking. He said he was going to have to cancel the booking.
He then proceeded to try and get me to cancel the booking leading to me being charged for canceling.
After calling Airbnb and putting in a request because he stopped communication after saying he will be canceling I was refunded.
Beware of canceling for the host, if he cancels the listing you should not do it on your side of the app.
