Great location, especially when you want to explore Amlafi coast, Vesuvio, Pompei or orher spots around Naples because you dont need to drive via active city center with a car. Its also really close to the airport.
Cafeteria is 1min from apartment, supermarket (works from 8AM) is 2min from apartment and in Piazza Nazionale 5min from apartment you can find Gelateria, Bakery, Pizza place and other restaurants. Public transport station is close and city center is reachable by feet too.
Host from Naples gave great recommendations for places to visit and eat. If you are into trying Neapolitan cusine - Tandem restaurants are a must (recomended was in Via Paladino)!
P.S. Neighbours are nice and friendly too!
