We stayed one month in Vincenzo's apartment. It is located 15 min walk from the central station, 15 min walk from Molo Beverello port (slow ferry to Capri and Ishia). The neighbourhood is a bit overwhelming, but can have its own unique charm.
The apartment is spotless, everything is functional and the mezzanine bed is a great touch. Vincenzo's father was a splendid host, he offered to come give us clean sheets and towels every week, and was very reactive to any issues during our stay. COVID hygiene was top notch, with our own 1 liter hand sanitizer bottle and fabric disinfecting spray.
We would absolutely recommend this listing for a stay in Napoli.
