I spent ten nights at Ornella's apartment and highly recommend it. It is hard to imagine a better location. The apartment is between the historic center, the main shopping street (Via Toledo) and the port. Everything is easily walkable. The apartment itself is very clean, nicely decorated, well equiped and spacious for one or two people. It is only one short flight of stairs from ground level. Ornella and her son Lucca were warm and very helpful with small issues that came up (working out delivery of my lost luggage, great restaurant recommendations, etc.). Communication is fast, with perfect English. There is some noise from other people in the apartment building, so you might want ear plugs if you are sensitive. I would definitely stay here again if I'm back in Naples, which I hope to be. It's a great place to stay!
