The stay at Freddy's apartment was very pleasant. Freddy is a great host, he provided us with some kitchen essentials like water and milk to begin with.
He answered very quickly and was always concerned to make our trip as nice as possible.
The apartment itself, despite being quite small, is highly recommendable. The rooftop terrace offers a great view over the city and is the ideal place to enjoy a glass of wine after a joyful day in Palermo.
Regarding the sleeping couch: we found it very comfortable and slept well in it.
