My husband and I were Superhosts for Air BnB for about 3.5 years with a 5 star rating. We had a guest who filed an issue with Air BnB and we were permanently and immediately deactivated as hosts and the ability to book as guests at other locations. We were told they could not tell us, for confidentiality reasons, the person who filed the complaint or what the incident was but asked us what we could tell them about the incident. Several times we explained we were not aware of any incident from any guests so how could we address an incident without more information. We tried multiple avenues to have this reviewed, but to no avail. We feel victimized by this situation and feel that Air BnB does not have a mechanism in place to ensure the complaint was accurate and legitimate. They based their decision on one-sided information. We had invested much into making our accommodation a great destination for Air BnB guests and that was taken away abruptly with no recourse on our part. Everyone deserves to be treated fairly and we do not feel we were given due process in this situation. In addition they immediately cancelled all upcoming bookings at our home and those guests were given no information as to why their reservation was cancelled. We had guest who had booked 6 months prior and were arriving in 2 days who then thought it was us who cancelled them. Air BnB gave no assistance to them in finding other suitable places. Totally unprofessional in my opinion.
