We really advise people, and specially young people, who search for authentic experience of Italie and Sicily to AVOID wonderfull Italy.
These gangsters tried to charge us 350 euros for the storm destruction of there shutter and send airbnb pictures from our garbages... Samuele, the guy in charge of hour appartement was really rude and didn't gave us any good place, exept for super-touristy, to visit.
if you want to offer luxurious and authentic places, then you could at least behave respectfully for your guests so they do not notice what you are: A TOURIST SCAM.
