The Residenza was a great place to stay for our visit to Napoli. A supermarket is nearby and the main pedestrian street just around the corner. It is amazing to sit on the roof top terrace with a glass of wine after a sightseeing day. Good pizza and bars for an aperitif are also just around the corner.
Be aware that you have to leave at 9am in the morning at departure day but the luggage can be stored at the flat.
