We spent 4 wonderful night's at Massimo's apartment and loved it! As others have said, the apartment was incredibly clean and even more lovely than in the pictures. We loved the view, high ceilings, shower and very comfortable bed! Massimo was indeed a super host - we arrived late on the airport shuttle, around 10:30pm, and he picked us up in his car to take us to the apartment and greeted us with cannoli and peach tea :)
We do not speak Italian and Massimo has limited English, but we still managed to make ourselves understood and Massimo shared wonderfully helpful tips for the best places to eat/drink/visit. Communication before our visit and during was very prompt and easy.
We loved the location of the apartment in the tiny back streets - it made the apartment a little hard to find on the 2nd night after dinner, but all part of the fun! It is in a great location by Capo market and the Teatro Massimo. All in all, it was fabulous - if you're coming to Palermo make sure you stay here!
