Nice little clean place to stay in. Flat is not luxourious but nice for the area. The Spanish quarter is a buzzing old area. The flat is 4-5 minutes walk to two metro stations and the port to sorrento Capri and the Amphi cost. Two metro stops from main Napoli train station and easy access to other attractions.
There is one flight of stairs and no lift. Plenty of places around to eat. Host was very nice
