@Ольга60 If this host is being unreasonable and trying to charge you for something you didn't do, just decline to pay. The host would have to prove to Airbnb that the place was left a mess with dated photos from when you checked out. I looked at your profile, and all your past reviews say you were a good guest who left things clean and tidy, so I don't think you need to lose any sleep over it, and even if the host writes a bad review saying you left a mess, you can always respond to the review, just stating that the review isn't true and for hosts to please look at your other reviews, which will make this evident. As a host, if I saw 4 or 5 reviews stating the guest left the place clean and tidy, and one that said the guest left a big mess, I'd dismiss that bad review as being untrue, or at least ask you about it if you requested to book.
