Gianluca's place is great!
We loved it. Its very spacious, it can fit up to 6 people and he will make the sofa a bed for you if you need it. He is also always available in case you need anything. Don't let the fact that this place is not close to the main monuments keep you from staying here, it is very close to the metro station and it makes life much easier.
Gianluca was also very patient the night of our check-in as our train was delayed 2 and a half hours, but he didn't mind and waited for us in the airbnb even though it was almost 11pm.
The apartment is very cute, welcoming and tourist friendly! He has maps of the city and recommendations of places nearby.
