We enjoyed our stay in this nicely located ( just outside the busy touristy centre) apartment. It is small, especially the bathroom, but for the two of us was quite workable. Enquire about the heating if you're there in the cooler season as we found it too cold overnight in late October and couldn't get the heat on. There are some nice restaurants nearby, and the Villa Borghese. The main part of old Rome is entirely walkable, it's 4 km from the apartment to the Coliseum going south and 3 km to the Vatican going west. Everything you want to see is in that triangle. Getting to the apartment from Termini is a breeze, Metro then 2 stops on the tram if you're carrying luggage.
