I didn't meet Luigi since I arrived late and was out of the apartment during most of my time in Palermo, but Luigi was incredibly generous, texting me to make sure things were going well, and making me feel welcome in his apartment. His nephew, who lives on the first floor, was also very kind, gave us the keys, and also helped orient us in the city. The apartment itself is great: quiet, in a lovely part of town in the very center of Palermo, and there is even an elevator. But the best part of course is the balcony, where you wake up to the view of the churches and other historical buildings of Palermo. Highly recommended!
