I only stayed one night at Marco's place during my short stay in Napoli but enjoyed my time there. Marco not only provided me with lots of information prior to my arrival but also gave me great suggestions on some of the more scenic places to visit in Napoli. He also recommended Sorbillo's pizza restaurant... the best pizza I've ever had in my life!!!!! It was to die for! :)
The flat is nicely furnished and renovated and in a nice area close to the university and public transit.
Very nice place and awesome host! Highly recommended!
