We stayed 6 days at the Viola apartment with my husband and we definitely recommend it:
The apartment is calm in a quiet street. It is perfectly located, we could sightsee all the main places in Rome by walking : center (Navona, pantheon, Trevi…), Coliseum, Trastevere, Vatican…
The apartment was clean and well equipped. Emiliano and his team responded fast and really tried to make our stay perfect.
