Dear Claudio, thanks for your review. We will consider your comments.
To all other readers. The rating given by Claudio is considered a "revanche review" There was an inconvenience at the arrival of this particular guest, we have offered him a compensation, had Airbnb to mediate in this, came to an agreement and in the end we've received a 1 star review. During their stay our hostess has been to the house various times and the Claudio indicated that everything was fine, clean and perfect.
Luckily all other reviews received are good and we have only happy guests staying with us.
