Roberta was a fantastic host, she kept in regular contact before the trip and kindly asked if we needed any assistance getting from the airport. Unfortunately we didn't get to meet Roberta but she had organised for her sister to come and greet us instead so it was no problem.
The apartment was great! It looks exactly how it does in the pictures - very clean and spacious, perfect for a weekend stay. It is around the corner from Campo Dei fiori, a lively square with lots of restaurants and bars and from there all the major sights were within walking distance.
A great stay in Rome - would definitely recommend staying here!
