Ariele' place is perfect for a couple looking for a quiet Roman neighborhood in a great location to get all the sights. It's clean, comfortable, and Ariele is incredibly accommodating. He allowed us to check in early and called a driver for us to get to an early morning flight.
The apartment is at the top of a stairs only building, so be warned for anybody with ailments that make stairs difficult. If you don't mind a bit of exercise and don't have an injury it really isn't an issue.
The neighborhood is fairly close to a bus stop that has connections for buses that go all over the city and it's easily walkable to Trastevere, Pantheon, Trevi.
Overall, I would absolutely recommend this place for anyone looking for a quiet place in a great location.
