This was my recent experience with CheckMyGuest. CheckMyGuest is a €1.5 billion group who claims to have had hosted 950,000 travelers (proof) in 2022. Despite their size, their level of negligence, incompetence and lack of basic customer service makes even the worst fleabag motel look like the Ritz in comparison to their operation.
To be fair, Airbnb support tried right away to be helpful; they offered to move me out of the unit and even offered a relocation credit. However, due to the busy season and the last-minute nature of the search, there were no comparable apartments available on the same side of Paris.
