Highly recommended, especially for family travels!
The apartment is in the ZTL zone, so you have to get a pass to enter, it's better to check it with the host before your arrival. The parking at the square in front of the apartment is free and safe.
Almost all the attractions are within walking distance, so you don't need to drive a car since the traffic situation in Palermo is not that good.
The supermarket is not in the city centre, but you can find many grocery stores near the apartment and many good restaurants on the pedestrian street.
The apartment is very chic, artistic and well equipped, many decorations are Paolo's artwork, very impressive! Paolo and Valentino are very kind and warm, they will give you much useful advice for exploring Palermo.
