My daughter and I stayed in this apartment for 5 nights. It is a small basement apartment at the bottom of a former 1901 hotel building (now private apartments), so it has no outlook and is dark without the lights on, but it is comfortable and well-equipped. It has a comfortable double bed, and a good sofa bed in the living room.
Bruno collected us from the airport the evening we arrived (same cost as a taxi approx) - well worth it. He gave us an excellent guided tour of the main city highlights, showed us where to find the metro stations for the main sights, and gave us a potted history of the city. His knowledge of and passion for Napoli are superb. Bruno and his family live in the same building, and communications were very easy.
Anything the apartment lacks in style it more than makes up for in location. A good, safe area with very easy access to metro, funicular and buses. All are cheap and easy to use. Easy walking distance to the beach and local shops etc. Great area to stay and an excellent host.
