Gianni was a wonderful host and the apartment was very, very nice. The main reason I came to Naples was the pizza, and his flat is within a 10 minute walk of some of the best pizza places in the world! The place really is almost connected to the Duomo, right in the heart of the city. It was very easy to walk to almost anywhere I wanted to go from his place. It is about a 20 minute walk from the train station. The room was nice and private, though there are other rooms in the apartment as well, with other guests. Gianni himself was very easy to contact and responded to both emails through the site as well as text messages, and was very pleasant to talk to when I got the chance. I would highly recommend this place.
