Many hosts consider anyone entering the unit , even just for lunch or dinner, to count against the listing "max", and accuse you of having a party. and some are quite big brotherish about monitoring.
Last month a first time host confabulated $1200 of maintenance charges. Having left the property already, I was in no position to produce evidence that they were fake. Arbitration was hopeless, I canceled my card and won't be using Airbnb again.
Funnily enough I went through something similar 3 weeks ago at an Airbnb in France.
The host retaliated because we had the audacity to tell her that the place was unclean when we checked in. She claimed 2000$ of fabricated damage and as you Airbnb sided with the host initially.
It's only because I lost 3 hours of my time with support and took a thousands of screenshot from our Messages that I got them to drop that charge.
I also issued a Chargeback with my credit card for the dirty place.
But yeah, this is done for me as well. I had 20+ stays but I will never , absolutely never use them again. My time is worth something and this Airbnb destroyed our holiday and took way too much of my time to handle.
