Sergio's apartment is located near the Garibaldi central station (metro/bus from the airport), near Circumvesuviana lines for Pompei or Amalfi (Porta Nolana) and is a few minutes away from city center by foot. The neighbourhood is ok, we didn't have any problems. The apartment is small, with small kitchen, bathroom and bed, but it has all you need and it was a perfect hub for our 5 days stay. Sergio is a great host, he checked in with us a few times to see if we needed anything. Naples is a city that you must see for yourself. It is noisy and dirty but at the same time it is charming and simply beautiful.
