Airbnb is so afraid of losing revenue that it is, as others have noted, deleting negative reviews. I stayed in an Airbnb in Atlanta that operated more as a rooming house and had a refrigerator full of old food that smelled so bad I would run in the kitchen to microwave coffee and then run back out.
In my review, I talked about the neighborhood (fine), the room (also fine), the other guests (fine), and the gross smell emanating from the kitchen (not fine). Then I learned that Airbnb took down the review because it didn’t meet their “Content Guidelines”.
Does it get any more absurd than that? The reason I had this awful experience is because Airbnb is censoring reviews that might have alerted me to the situation. They don’t care if you walk into filth. They just want to keep their numbers up. I’m really getting sick of dealing with this company.
