I stayed a month in Claudio's flat. The flat itself is very spacious and well equiped. I really liked the decor and the kitchen which allowed to cook a lot. The building is nice, although a bit far away from transportations. I usually walked for a bit to the historical center, train station or Piazza Carlo III, but I really felt at home at Claudio's. He was very nice, especially for my arrival. I would recomment staying there, the flat is great if you are planing a long trip and want to experience Naples outside of where all the tourists stay.
