Great apartment, great location and very nice host.
The apartment is spacious and has to bathrooms and location is very, very good overlooking a cozy piazza close to everything you need with a local atmosphere.
One note is that the piazza attracts quite a few people during evenings (we stayed a weekend). After walking Palermo for a day neither of us had any problems sleeping through it, but if you are sensitive I'll advise you to join the crowd. or you might just have the experience of the chatty Palermo nightlife at your bedside.
All communication with the host was fast and easy and everybody was very helpful following us to a parking house.
All in all very recommendable and we would stay there again
