My wife and I spent a month in this apartment. Everything was great we both were working remotely so the Internet speed was ok to work. My favourite room was a guestroom and the inner garden where we were eating( there is an excellent place to get food or an ice cream 3 minutes to walk and incredible working time from early morning till late night ). Davide is a very welcoming owner that always supported us with all questions that we had. The location is great there is a wild beach 2 minutes walk, Mondello 15-20 minutes walk or 5 minutes by bus or car.
Palermo city centre is also not far 40 minutes by bus. If you have a car you will not face a parking problem near the apartment as if you were renting it in Palermo centre or Mondello.
