We couldn't imagine for a better host than Pietro. He was very kind and helpful, gave us so many advices where to go and what to do. The recommended restaurants are a blast! Pietro was always available and even organized our tour to Etna and the shuttle back to the airport.
The apartment was very cozy and in a small street near Via Etnea. No traffic at night, but still in the Center, couldn't be any better! I highly recommend you staying at Pietro's place to enjoy Italian hospitality.
