For visiting Palermo you cannot find a better location. It is in the heart of the center. On the balcony you can see theatre Massimo (150 m). Everything we wanted to see was on walking distance. The neighbourhood is clean and cosy. In the small streets there are lots of restaurants.
Our host (son of Fabrizio) was very friendly and picked us up from the busstation. He also gave us tips about good restaurants and was helpful in finding the right bus to Mardello beach.
For breakfast there was plenty of food and fruit.
The only minor thing is that it is a bit noisy.
I would certainly recomment this apartment for visting Palermo.
