We had a great time here and in Rome. Ilaria set us up with a crib and the place is a 5 minute walk from one of the only playgrounds in Rome, so worked perfectly with our 2 year old daughter. It was a lot of stairs as beyond the 3 floor walk-up it was 2 more flights of stairs to the main bus stops, but that was good for burning off the gelato.
We did get off to a slow start the heat being off when we arrived during a cold rain and Ilaria's brother seeming not as familiar with the place as was needed (e.g. what to do with garbage). But in the end it was all resolved and Ilaria was extremely prompt and helpful. Definitely recommend!
