We spent a great holiday in this apartment- it is spacious and very clean, very comfortable for a family with kids, with everything you need for a comfortable stay (if you have a stroller take into account you have to carry it up one flight of stairs).
The neighborhood is out the center of Rome but the main attractions are within walking distance (25-60 minutes) with very convenient public transportation (train/bus/tram) a few minutes away.
There are restaurants and supermarkets right under the building and the hosts are helpful and accommodating.
Definitely a good choice for a holiday in Rome.
