Apartment was very clean and bright, there were everything you could need (plates, towels, shower cream, etc.). From the balcony there is a great view to San Pietro. Near the apartment there is a railway station (San Pietro) from where you can easily get to central station (Roma Termini). During the day it can be a bit noisy because of the trains but during the night there is no traffic.
The host of the apartment was very kind and helpful, recommended to us a good places to eat and helped to order the car.
I think it is a great place for families.
