I got surprise roommates once too. An entire family living in one of the bedrooms in what I booked as a 2 bedroom unit. Turned out the place had 3 total bedrooms, and while I would have understood if the host lived in the third, this was a totally unrelated tenant with multiple children. I contacted Airbnb and they said sure I can cancel, I just need to get the host to agree. Which he obviously did not want to do. This took hours to resolve.
