I had same experience with my guest today. The guest is complaining about everything and also is asking for a refund of cleaning fee.
All my review for that apartment are five starts and the guy gave me only one star today.
Hd is complaining about things that it is simply not true- like that I have cockroaches, that apartment was very dirty etc. he doesn’t have any documentation.
I called to Airbnb asking to contact the guest if he can provide some picture of cockroaches, sorry bedsheets etc but Airbnb refused to do that. They can not delete any reviews or ask the guest to prove it.
after hosting a few years and being a superhost with 400 reviews I really feel very disappointed. Airbnb does not offer any protection or even support. The guest can write whatever wants, it’s their right.
It’s very sad when your guest is simply a conman 😞
