This was the best experience we have had with Airbnb stays and I would recommend it without hesitancy.
The apartment was exactly as described, three large, well appointed, en-suite bedrooms, spotlessly clean with a bright dining/sitting area. Each bedroom and the dining area had their own airconditioning and TV. We had three sets of keys which allowed us to come and go separately when we wanted.
The location was perfect with most of Palermo's tourist attractions within easy walking. The apartment opens from a private courtyard. There are numerous bars, restaurants and cafes on the surrounding streets.
The greatest asset is the host, Antonio. We had been in contact before our visit when he recommended and booked a parking garage for our week-long stay. He registered the necessary ZTL driving permits. He greeted us on arrival and was available all week to answer our questions. He was the perfect host and we are grateful for his help. The bottle of wine on arrival and almond cakes during our stay were nice touches.
It would be helpful to Airbnb if they would compare and contrast our experience with Antonio, with our very poor experience in Perugia with Matteo and Patricia.
