We spent 4 nights at Roberta's apartment. It was a great stay overall. Roberta was very responsive throughout the whole process - before and during - and offered assistance with travel plans. the apartment is greatly located, a 15min walk from St. Peter's, 30 min walk from the Forum/Colosseum. Moreover, it is located in Trastevere - a neighbourhood filled with restaurants, bars and unique boutiques. We were a family of four - 2 boys early teens. While small compared to North American standards, the apartment suited our needs very well. The second bathroom was great. Highly recommended.
