@Matthee1 Then the only thing I can suggest at this point is good communication with your host. I'd be upset too, if what you've described happened to me, but if you explain your end to the host, you both should be able to work something out. I'm hoping that it's simply a misunderstanding on the host's end about how their listing should be set up, although that's not really a valid excuse.
It's never good to start a reservation with animosity on either side, so I hope you and the host can manage to communicate pleasantly and come to an understanding.
If I were the host, I'd waive those charges. The fact is, if you bring this to the attention of AirBnB, the host will likely be penalized. If your true intention is just to have a nice getaway with family and friends, definitely try to work this out amicably.
Good luck!
