We spent 3 days in Palermo at Sandro's place. It was perfect. He prepared lots of informations, maps and recommendations for us, very helpful and kind. Sandro is "molto simpatico" and do everything to make you feel comfortable. Even make us try pastries from Sicilia (thank you by the way, it was very good and eaten fast !!)
The apartment is very nice, big, and clean.
The only small inconvenience could be to park the car. It's a bit complicated to find a space at some hours, and with Sicilian traffic, you need to be reactiv when you find a space. But once parked, the neighbourhood is safe, with some restaurant nearby, and close to the city and beach by car.
We enjoyed very much our stay! We recommend Sandro's apartment!!!
