This is a perfect place to stay for a small family or even two families staying together. We loved the room that has an upper loft style area with 1 small toddler bed, and a full size bed. It is perfect to have the parents sleep in the room with their kids but feel like there is enough space that it isn't crowded.
The living room with the projector screen that drops from the ceiling was an added benefit. The kids were able to watch some movies using the provided dvd player and dvds while we were there. It would have been great to have a chromecast or some way to connect in our electronics to watch movies from our ipad or laptop. There was a basic 3.5mm plug to pipe audio through the ceiling speakers though we didn't use it.
The rooftop area is a nice place to step outside, there is seating and shade areas to sit. We weren't comfortable with the kids playing up there in case they climbed over the fencing but otherwise they enjoyed running around in circles in the space. Nothing to worry about for most people, just that one of our kids has no fear of death so we don't trust him.
There is a grocery store that is about halfway between the place and the train station. We stocked up on drinks and snacks there. There is a great gelato place to the north-west and a few restaurants within 2 blocks.
In summary, it was a great place to stay and we would recommend it to family or friends if they are traveling to Rome and want to stay together in a rental versus 2-3 hotel rooms.
