Hi @Aristides0
This guest was throwing up all sorts of red flags. I would have asked Airbnb to cancel well before her arrival.
I am not exactly clear what you are saying she wants.
In your situation
1. I wouldn't refund this entitled woman a bean
2. I would let her know she is welcome to cancel. She needs to contact Airbnb to do so. They will handle any refund due.
3. If you like say you are happy to be flexible and generous and that if Airbnb allows you to keep any of the fee after she leaves, if you get a replacement booking, you would be happy to consider a refund.
She will leave you a terrible review anyway so don't feel blackmailed by the threat of one.
