I spent a week in Giovanni's apartment.
Well located - less than 5minutes walk from the main train station which I used for visiting Sorrento, Pompeii and Herculanium.
Most of the attractions within Naples were within walking distance.
A large room with a big bathroom.
Everything was clean, plenty of hot water, good wifi connection.
Small supermarket just round the corner (Piazza Principe Umberto).
I can thoroughly recommend it as a base for exploring the Naples area.
