Francesco is a kind and friendly host. He helped us with the luggage because there are many stairs to get to the flat. Thanks a lot ! About the flat: it's in the middle of the historic center of Palermo: this means, really the old historic center. It's well located but on my opinion I didn't like the area and Palermo at all.
Anyway, I recommend the flat of Francesco and I'm very grateful because of his hospitality.
