Marzia's place is the perfect location to enjoy everything Rome has to offer, there are so many great restaurants/bars/cafes within a short distance. Its located right in the Piazza Santa Maria in Trastevere where I think most of Rome comes to celebrate the weekend. Lots of street life and with it a lot of noise but we did not mind it. You can easily walk to any part of the city but if you are not up for walk there taxi stand a short distance away. We were a family of 5 and it was more than adequate especially with the terrace.
