@Panagis0 unfortunately it is possible and it is a mystery to me how Airbnb still hasn't done anything about this after years and years of hosts complaining. I don't think there is anything you can do and Airbnb won't remove the review if ut isn't against their policy.
@Panagis0 this is a bad review because the overall rating is what actually counts and as I said, I doubt they will remove it but you can still ask. Don't worry too much though, you will get a lot of good reviews soon enough.
