Me and my boyfriend had a nice stay in Fabrizio's house! Communication was very fast and accurate, the location was good. A piece of advise though: if you arrive from the airport and take metro, you will be switching the metro stations from Montesanto to a linea 2, for this you have to physically leave the station and walk a block! Check on the map or ask nice Napolitanos hor to get there. Then once in that station take a train for Cumana which is on your left of the train lines and from tehre it is only one stop :)
The house was nice, clean and cool, in summer it must be a blessing, it is a bit dark, but we didnt stay in the house too much.
The kitchen is a bit basic if you planning to cook a lot -only one stove ring.
We were walking a lot and there is a straight road that takes you to the flat - Corso Vittorio Emanuelle. You might find some metro trains a little intimidating hehe, give it a try though.
Thank you once again Fabrizio for being a lovely host.
