When I was in Naples the last (and only other) time, I stayed in the ancient part of the city, on Tribunali. It was noisy but I liked it. Now I'm having a hard time finding a rental in that area. What other area of Naples would be recommended for a tourist? We won't have a car, and don't want to spend all our time in busses and trains, so I'm looking for somewhere that's walkable to lots of interesting sites. Any suggestions?
