Salvatore's apartment was just perfect. Ideally situated with a spectacular view, we stayed a week and didn't want to leave! Although it's close to the street, it's not too noisy at all. The shutters block out the noise and light very well. Lots of excellent restaurants nearby and just a two block walk to the Duomo.
In addition, Salvatore and his daughter were excellent hosts. We've stayed in dozens of Airbnb places around the world and I can say without a doubt this was one of the best...both places and hosts. Highly recommended!
