In 2017, I was touring Europe with my bicycle. I camped most of the time, but it was quite cold and rainy during a week in September. I decided to stay with Airbnb. The first night went quite well, so I made another booking the next morning. It was 60 km away, in a small village in Germany. Instant Book was enabled, so I immediately got a confirmation.
I set off and reached the address around 5:00 PM. When I rang the bell, there was no response. I messaged the host. After approximately an hour, the booking was canceled, without any explanation. It was cold and getting dark fast, so I headed to the nearest hotel. It was only five kilometers, but with the rain and the mud, it took me another hour to get there. At 75 euro, it was much more expensive than some of the other hotels I could have stayed with. Later Airbnb messaged me, saying the host enabled Instant Book without realizing the implications. They kind of blamed me for choosing a host with little experience and did not offer to pay part of the hotel bill. They have much more data on the host than me. They should not allow inexperienced hosts to enable instant booking.
