Nunzia's place was very accommodating. Spacious, clean and organized. The kitchen was well furnished with everything you need to cook a meal (no microwave though). Tea, snacks and other things were left for us. After thoroughly showing us the apartment, Salvatore gave us useful information about Naples and the surrounding areas and what to do and where to go/not go. Some of his tips were very helpful to us.
The apartment is two floors with only the bedroom on the second floor. This means walking through the house to use the bathroom, but it's not a big deal for us.
The apartment location is in a side street (which was a little hard for us to locate every time we wanted to go home, but it's not a fault towards this place - Naples was just hard for us in general). It's on the 4th floor, with an elevator running up and down. Unfortunately, you have to pay 10c to use it; fortunately we need the exercise so we chose the stairs every time.
The apartment is about a 10 minute walk to the Naples Central Station (there are two routes you can take, one takes you through a sketchy area which we took initially - Salvatore informed us of a safer option). Salvatore also offers taxing services if you need it.
Overall, our experience was positive and not just because of the apartment. Our host was part of the good experience.
