Marco is a super host, very reactive, who greets you in person and gives you plenty of advice. His apartment is like on the pics, pretty spacious with 2 bedrooms, set in a quiet area although central as ideally situated (3 minutes from metro line 1 / Università, so handy to go to the station, close to the old historic centre and the port should you want to take a boat). A classy supermarket round the corner, and other shops close by too. The kitchen is fully equipped, although we didn't use it, but for breakfast and an excellent Italian coffee in the morning - enjoying the local life, including the food, is our motto when on holidays.
Unless you have difficulty with stairs (2nd floor of an old Napolitan building), I'd recommend you to stay at his place, for the flat , but especially for Marco himself, who is probably the best host I have met so far. That's real customer service! ;-)
