Our time at Giusis apartment was very nice!
The location is very central (5 Minutes to the next train station and about 10-15 to Theatro Massimo) and there are a lot of nice restaurants and bakeries around (Giusi provides a lot of information when arriving in Palermo).
Although we had serious trouble with the WiFi (connection was very unstable during our stay) Giusi and her family tried their best to fix it and to find alternatives to make our stay as pleasant as possible. She was always responding immediately to our needs and always asked us if everything was ok.
