Andrew's place was absolutely perfect.
Just between the Capitol (museum), Tabularium, and the Forum, we couldn't have dreamt of getting anything better located: A quiet island in the middle of Antique Rome. It's really within walking distance of everywhere (the River Tiber and The mouth of Truth are 200 meters away). Being a bit away from the main arteries, we felt like local residents.

The highly rated local shop: I fienili di Pannella Carmela is 50 yards away.
The flat itself is well equipped and we were able to use the kitchenette, and the shower is powerful.
