We feel cheated. Host told us at the door that we had to pay 7.5 euros for 3 persons each day. This was never made clear when we booked this unit via AIRBNB. We feel cheated. She said it was a local requirement by the Police in Florence. We were also never shown the receipt of our payment of 22.5 euros we paid for 3 persons for the 3 day stay. Can Airbnb investigate and reply to us? If we knew we had to fork out this additional amount when we were looking for accomodation in Florence, we would not have chosen this apartment. I have used Airbnb for a few years now and this is the first time we were required to pay additional costs beyond what was advertised in Airbnb and there was no prior knowledge of this payment until we reached the door of the apartment!
