Massimo's apartment is very well located, near the historical center of Napoli and close to the main station (Napoli Centrale and Garibaldi).
It's well equiped and Massimo left everything we needed for breakfast and more (soap, water, fruit juices, biscuits, oranges...). He even came to check everything was going fine, and bought us delicious pastries!
Also, Massimo gave lots of advices for restaurants, cafés, bars and places to visit.
Compared to what we've seen during the rest of our Italian trip, we highly recommend this place!
