We had a great time in Naples! Marco's apartment was in a residential building, and oh-so-close to some of the best pizza places in Naples (according to Marco *and* Rick Steves - and me!).
There weren't very many English speakers in the area but people were very friendly and helpful: someone in the apartment building helped us with using our key in our door; the owners of the market up the street when we wanted to buy some dinner; the wine store and the pizza parlour.
And Marco was so very helpful with our stay. He was easy to contact and offered advice when we needed some direction.
Grazie Marco!
