Fabrizio's apartment is located on the main Street of Napoli which is where all the shops, restaurants and attractions are. You can find all sorts of stuff you want. It's only 20 minutes walk from the two castles and the seaside which makes Fabrizio's place perfect for all sorts of travellers. Fabrizio is extremely kind as well and replies to our SMS promptly ! He also offered to take us around on our last day but we had other plans. The wifi could be better though otherwise this place is the best.
