A perfect place for a family with two kids. loads of space and a big terrace to eat outside.
It's not too far from the metro station. If you want to visit the center of Rome you will always need this because it's not in the center but just outside. We walked twice to the vatican in about 40 minutes. There is also a taxi stand close by. With a taxi it's about 20 minutes to Flumicino airport (outside rush hours).
The advantage of staying just outside the center is that it's quieter and the restaurants are less flooded with people.
