The apartment is awesome, bigger and more beautiful than in photos. We had stay a family of 5 with teenagers, and each one has his/her own space in the apartment, with an own TV in each room, and 3 bathrooms, that avoid discussions. It is so beautiful but functional at the same time.
The localization, I think it is the best in Rome, because everything is at 10 min walking or you just can get a bus around the corner of the street that take you to anywhere in Rome, in a quiet street but a lot of restaurants and services around.
Sara was a fantastic host, always available for our doubts, and she made our stay easier with our earlier check-in and the arrangements for the airport shuttle service.
We will stay again in this Apartment when we come back to Rome.
