@Bert8952 It is a lot, but I agree with @Alexandra316 that it's best to avoid getting into the weeds of that topic with your guests.
It's been my experience a few times lately as a guest, that I've considered booking a place through Airbnb but ultimately found the exact same place listed elsewhere with a much lower total price. From the guest perspective, I can't think of any "service" Airbnb offers that is worth that discrepancy.
