The apartment is a great option for staying in Napoli. Luigi's mother took great care of us, with very elaborate Italian breakfasts and attentive care. I've never had such nicely folded laundry! Air-conditioning and laundry are included for an additional charge, as notes in the details, but both are very reasonable.
The apartment is located on a main street close to the metro, but il centro of Napoli is very walkable and easy to navigate. Not far from the apartment is the lively neighborhood surrounding L'Orientale, with many bars and restaurants and other venues. Via dei Tribunali is not far, and the walk to Via Toledo/Piazza Dante, Quartieri Spagnoli, the port and so on is not bad at all. Highly recommended.
