We really enjoyed our stay in this cozy apartment right off the Piazza Navona. The space is small but doesn't feel cramped and easily makes up for any lack of space by being right in middle of everything Rome has to offer. The neighborhood is very lively and is an easy walk to all the major attractions. Its also not hard to get to by cab if needed.
Daniel and his team were incredibly helpful with offering to arrange car transportation to and from the airport. We had an early flight out of FCO and they had a car waiting at 5:30am to get us there on a Sunday morning.
The apartment is on a small but lively side street so its quieter than most of the neighborhood but there's still a lot of activity outside in the evenings. We really enjoyed feeling connected with the neighborhood in a way that only AirBnb really offers. Its not for light sleepers though.
