@Bouakham-and-Henri0 Both of your messages are a bit incomplete/confusing. You mention that the guest asked you to cancel, then you mention that the guest "lose all", b ut you never said if the booking was actually canceled. Or, if so, whether you canceled (I hope not!) or the guest canceled.
If the guest canceled, which is what I'm assuming, that's how AirBnB will know thata they never arrived, and, thus, won't be able to leave a review. (If *you* canceled, the guest would've received their money back -- and therefore wouldn't be complaining to you -- and your listing would have been "punished" by AirBnB.)
