Very nice apartment directly in the historical center of Naples, 20mins walking to Napoli Centrale&Porta Nolana, so it's ideal if daytrips to Pompei/Vesuvius are also planned. Since it's not directly at the street, it's quieter than the location would suggest. A bit further away from some of the sights close to the water but that's a compromise you'll have to make.
The apartment has everything you need for a nice stay and check-in and communication with Stefano&Gianluca was immaculate. I can fully recommend the place.
