In terms of location to historical sites in the city, Alessandra's place is central. Bus no 916 which stops near her apartment will take you straight to places like the Spanish steps and colosseum. We rented a car and parking is not a problem and it is free.
We brought our kids ages between 11-15 years and they were a bit noisy, and the neighbour downstairs complained. So if you do plan to bring your kids, make sure they are quiet at night. Overall We enjoyed our stay at Alessandra's place.
