The apartment is great for larger groups, we had 4 adults (2 groups of 2) and 2 kids. So the 3 bedrooms and 2 bathrooms were great for the group. The apartment was clean, and looked really good (well designed). The location is perfect, right in the center of Rome, near the Trevi Fountain.
The walk up to the apartment is a little tough, 4 stories, but there is a small elevator you can take.
