We loved our stay at Sarah's apartment. It is very spacious including 2 very large bedrooms. It has all the amenities that you need. It's very central, a couple min walk to the metro and around 10 min walk to the Roma Termini (main train station) which was very handy because we were getting a train to Firenze/Florence as our next stop. It is on a busy street but the windows are very sound proof, it was no problem even with my young daughter. The only thing I will point out is if you want to let fresh air in through the windows, the outside noise is quite loud.
