Yeah, like the host doesn’t care anyway, he won’t get any money only until after something like 2 days after check-in, so paying directly at the site should be no problem for a serious host. I used Airbnb 5 times and 3 of those hosts gave me their webpage and mail and said to come back but book directly without the airbnb nonsense. From my experience, most of them are small businesses too small to have an advertisement or to be covered by a reservation company like booking.com. They often register my ID with the ministry of interior and pay taxes. Maybe it is just because I have the wit to chose serious honourable people who do things legally, but that is at least my experience.
