Luca's flat could not be better located. It is steps from the subway line that will take you to all points of interest including the port and train stations. The neighbourhood is outside of the tourist area and is vibrant and interesting. There is a grocery store nearby and the local pizzeria and coffee places are great.
The room is a good size, newly renovated and very clean. Luca was very helpful, providing easy directions from the airport and many useful tips about the city. I would highly recommend staying here while in Naples.
