If someone deserves the Superhost tag, that is Sandro. He was very responsive and understanding upon my arrival, since I was having some issues to get my phone working and there was no way I could communicate with him. Once arrived, he kindly offered me some coffee, showed me the apartment and gave me great recommendations about amenities in the neighbourhood and around Palermo.
His apartment is beautifully decorated with vintage furniture and antiquities that he must have been collecting for years; it's not the kind of cheap stuff you find at first sight at any market! Otherwise, yes, one room and the dining room are a little bit dark, but there are two nice outdoor patios with jasmine shrubs where one can spend a full day reading, talking, drinking and enjoying life.
The neighbourhood is around 30 minutes walk from the historic centre of Palermo (though not the most pleasant walk in town), well connected by bus and very accessible by car, a good reason to stay there if you're planning to rent a car and move around Palermo and Western Sicily. There are plenty of shops, markets, supermarkets and restaurants nearby, being the "galletto" at Braceria Savoca, recommended by Sandro, one of the best dishes we had during our stay in Sicily (and that's a very high standard!!).
I would definitively stay at Sandro's place if back in Palermo!!
