The apartment is located in the heart of the city. It is spacious, clean, and have air conditioning which is very pleasant during summer. You have the metro/train station which allows you to reach different destinations : the port in 10 min if you need to catch a boat for an island or 30 min away from Pompei.
Also, Alessandro is the best host you can wish for : helpful, reachable and gives a lot of information about the city and its surroundings. He can also take from/to the airport.
Our stay at Naples was perfect, grazie mille Alessandro!
