We (family with two kids 15, 12 years) spent 6 nights in the apartment. It was very comfortable and spacious enough for us. I felt at home from the beginning, because it is styled very nice and modern. Everything is well organized and clean.
The apartment is located in walking-distance to the center. Bakery, supermarket and cafés are around the corner. Trastevere is vivid and full of nice restaurants (we had a really good recommendation from Francesca).
We would come back every time again!
