I completely agree with the other reviewers, Giorgio is pretty much a perfect host and his apartment is great for a stay in Palermo. It's almost in the center of the center, close to Quattro Canti and you can easily reach every place in the historic city center within a few minutes. Everything you might need like a small supermarket or a really great pizzeria is also close by.
Giorgio had organized everything perfectly for us. He picked us up from the airport, took us to an ice cream parlor where we could try gelato in brioche, when we got to the apartment there were even some groceries for breakfast the next morning. Giorgio also recommended a street food tour which we did and which was a great experience. I can only recommend staying in this place!
