Great apparent near St. Peter's square and the Vatican. Gianluca thought of everything for the house and it is very clean, kitchen appliances work well, has a washer with clothes rack for drying. Apartment is kept warm and he has worked very hard creating a real nice place for people to stay. Has working elevator which is nice if you have kids and/or heavy luggage. He helps with knowing how to get where you're going and can help you get to the airport if you have an early flight. (We had to be at FCO by 5am!-public transit isn't working at that hour and it's about a 30 min drive outside of Rome (45 min by metro/train), he set us up with a driver that was private, and cheaper than a cab).
One of the few airbnb appartments that we've stayed in that has a safe.
The apartment is definitely closer the Vatican City than to The Roman Forum and the Colosseum. Will have to take a cab, bus or metro. The bus stop is very close to the apartment though so it's really not that bad.
Highly recommend staying here.
