Really excellent location, great restaurants and bars close by. Walking distance to Spanish Steps, Pantheon, Trevi Fountain etc. Spacious and clean apartment, really great for Rome as usually the accommodation is tiny!
Note, the apartment is on the fourth floor with no lifts. It is also not close to the Metro line, so if public transport is important to you, then this may not be the place. We found it easy enough to walk around to most of the sights.
