Incredible place. Perfectly located in a walk distance from Capodimonte, Sanità, Catacombs of San Gaudioso and San Gennaio and on many of the major bus lines to the city center. Pay attention though, during the rush hours it's not easy to get a bus, and you can't always trust the google informations on public transit in Naples.
The place in itself is very charming, has a very nice terrace, loads of space, a very comfortable bed, and quite everything you need.
Luigi and his parents were very kind and helpful hosts.
