Centrally located, a couple of blocks north of Piazza Dante (up two sets of long stairs). Paola's place is clean and modern in stark contrast to the gritty city outside. She welcomed us with some breakfast items and a good list of restaurants to try in Piazza Dante. AC was very strong and the whole place felt safe and comfortable. I'd recommend it to other visitors.
It was our first time in Naples, and after our initial culture shock of the older part of town, we came to realize this is just the way Napoli looks. We explored the neigbhourhood late into the evening and had no issues.
