The Location of the apartment is amazing, in the heart of trastevere, close to nice restaurants, Bars cafes etc. Even all the attractions you can reach by foot. We didn't find it to noisy/loud, although the street was very lively.
Azzurra was also very helpful in every situation :).
The second bedroom wasn't as we expected it, and the shower pressure maybe need some renovation. But all in all we would definetely recommend the stay for your trip to rome!
