Valerio's flat is very central (close to city center as well as close to the harbor behind Castel Nuovo to take the boat to the islands and to Teatro Carlo to see Pompei) while at the same very quiet which makes a real difference when you want to rest at night after a day out. The flat was clean, safe and warm (it was cold outside in early spring). Valerio was a great host recommending many places to go to as well as the best traditional pizzerias in Napoli. Would definitely recommend it to anyone going to Naples.
