It's VERY good location of flat in Rome. It is quiet however it's in city center (3 km to Coliseum and 5km to Vatican), district with good infrastructure.
Flat has all needed conditions and quit comfortable. I like that it was not hot in flat while it was heat on the street.
Pay attention that late check-in (we arrived after midnight) coasted +40 euro (maybe it's normal for Rome :))
I recommend this place to stay in Rome!
