Apartment is close to metro station, 10 min walk to historic centre and about 15 min walk to central train station. Supermarket around the corner and shops and restaurants around the other corner so central for all locations.
The apartment was spotless and had everything we needed for our stay. It has a keyless system which is good as can arrive and leave at any time etc. Laura was very quick with any communication and very helpful when we needed to organise taxi to port etc. Map was on the table with local tips on it so very useful. Great place to stay in Napoli.
