This is a really, really smart and affordable apartment in a really cool part of town. The apartment itself is immaculate, clean and comfortable. It's also a 5 minute walk to the main bar and restaurant strip of Pigneto, a young and stylish neighbourhood that deserves its reputation as the Roman cousin of New York's Brooklyn or London's Dalston. Be advised, though, that getting into the centre of Rome for sightseeing takes around 30 mins by metro, and the metro stops at midnight (there are nightbuses though).
If you're mainly in Rome to see the sights and don't care that much for good food, cheap drinks and watching the beautiful people, this area probably isn't right for you. If, on the other hand, you're keen to immerse yourself in the atmosphere of the contemporary city as well as exploring its history, this is an ideal place to stay.
