Valeria was a very helpful and accommodating host, and I really enjoyed my stay at her apartment. The apartment was very comfortable and nicely decorated, and more spacious than I expected, with wonderful high ceilings. Despite being in a busy part of town it felt very private. It was conveniently close to the Termini station, and you could pretty much walk anywhere (I only took the subway to visit the Vatican, but walked back). The neighbourhood just to the southwest of the apartment has some really nice restaurants. I felt completely safe walking alone at night in the area.
