We are a family of 5 adults and stayed in Casa Bianca for two nights in August 2018.
The apartment was really lovely and although the "kids" two rooms were fairly small they were perfectly comfortable. The apartment was well equipped making it easy to self cater.
There is both paid and free parking in the street and we were fortunate enough to bag a free spot for the duration of our stay. The apartment is ideally located (outside any ZTLs) and approximately 1.5 miles from the center of Rome. We managed to visit all of the main sites in Rome in a day and a half on foot (although they were a bit achy by the end!).
Svetlana was very welcoming and helpful and we would definitely recommend Casa Bianca to family and friends.
