We had a really nice stay at Dinos apartment. We stayed there 2 adults with 3 large kids (9, 12 and 14 years) and the apartment was big enough for us all.
The apartment is in the center of Rome, just 100meters from the Campo de' Fiori square (which is one of the most charming squares in Rome, if not the most charming).
The apartment is reasonable quit (no traffic noise).
I would stay there again if giong back to Rome.
