Viviana is extraordinarily nice. Our train arrived with a 5h delay, but Viviana was extremely understanding and not mad at all. She awaited us with biscuits and Italian cake. Communicating with her was easy and fast. She was very helpful when it came to public transportation and, grocery shopping and restaurants.
The flat is very spacious, clean and has everything you need. Even though it is located near a busy road, the flat itself is very quiet. The center is easily reachable by bus (2 bus stops next to the apartment) or by metro (termini train station about 1km walking distance).
I would totally recommend Viviana's apartment to everyone wanting to visit Rome!
We had a great stay, thank you Viviana!
