We visited Roma for our short family trip (with 6 years old and 3 years old ) from Torino.
The location 2 mins walk from Ponte Sant'Angelo.
near the locations there are many cafe' and restaurants.
also about 10 mins, you have carrefour, if you like to get some grocery.
we loved the location very much since the space was bigger than we excepted our children had place to play their toys.
