We stayed 2 nights in Francesco's place. It is just like the pictures, a new apartment. Very clean and ameneged with everything you need (not Wi-Fi though).
It is close to the center (15min walk maybe or bus in the proximities). We were by car and the apartment comes with a parking place which requires some skills to park. We left the car there and just walked or took the bus, cause driving and parking in Palermo is a bit tricky.
Franceso and Rita are nice hosts, very friendly. Very flexible in check in and out times. Gave lots of local suggestions. Although he did not spoke any English, we were able to understand each other with the help of Google translator. We can only recommend!
