The location is very nice - Sferracavallo is a charming town, where you can find everything you need: local shops, dozens of restaurants, a little beach and one of the best gellaterias in the world. The communication with Palermo center is very smooth (20 mins by foot to train station, train go every hour), as well as with Mondello (20 min by bus, however the bus communication is a little bit crazy - you never know when, and if, you bus comes ;). The apartment actually is bigger than it looks on the airbnb photos and is nicely furnished. Giuseppe and the team are very helpful. They respond immediately to questions. I can recommend the place strongly.
