I'm not usually one to write a public review of places I go, but these guys and their lovely AirBnB deserve to be my first.
I honestly don't have a single complaint. The rooms are nice, clean and high standard. The hosts are genuine and extremely nice people. The area is nice and quiet, away from the more "touristy" areas, close walking distance to the Vatican.
We only spent one night there, but we wanted to stay longer and are gonna try to book a room at this AirBnB every time we are in Rome.
P.S: on recommendation from the hosts, me and my girlfriend had dinner at Bibi &Romeo, a restaurant 70 meters from the door to our room. It's the best Pasta Carbonara I have ever eaten. Do yourself a favor and have dinner there.
