You can't beat San Lorenzo for a unique Rome experience. It's a student and artist enclave not far from Roma Termini.
The apartment is a large studio with fully equipped kitchen.
As advised, the street can be noisy at night but settles down.
We enjoyed a great meal at Sanlollo restaurant a block away. The beer bar downstairs is cozy.
Don't overlook your transit connections including the tramway nearby and the 71 bus which takes you to Piazza Navona
