We stayed 4 days at Mauro's apartment. This appeared to be an excellent choice. Mauro is a very nice, hospitable and helpful host.
The apartment is very clean, very well equipped, including kitchen and bathroom and overall very comfortable. In particular, the bed is really spacious and very comfortable.
The location is really convenient. You have the historical part of Napoli within a walking distance. If you want to explore other parts of the city, a subway (Metro) is a great option.
There are 3 Metro stations within 10 – 15 min walk.
Upon the checkout, Mauro treated us with some delicious local cookies and took us to the ferry with his own car, free.
Highly recommended!
