I had a lovely room in a historic building in a very interesting neighborhood (a church with a Caravaggio painting is right across the building!). The apartment is a few flight of stairs up, and the elevator wasn't working, but Gianni came down to give a hand with my luggage. He was very friendly and helpful, and the apartment was clean, well-maintained and nicely equipped. One thing to note is that the place is a 20+ min. hike from Napoli Centrale station, and hauling a roller bag over the old cobbled streets can be a bit of an ordeal. However, you can take a cab from the station for around 10 euro.
