Location is very convenient, you can practically walk to all the sites in historic Rome. Next door downstairs is a small convenience store, across the street a small cafe for breakfast & coffee. Taxi stand is about 2 mins walk, we saw next to it there was a Metro station although we did not use Metro.
Only thing to be aware of, to reach the apartment there are 4 flights of stairs to go through, which are narrow in some areas. Also the bedroom could use a curtain (there were no curtains on the bedroom window). Otherwise the place is great, basic amenities were provided, Paola was a communicative and gracious host, the transport she arranged for us from Fiumicino airport to her place was reliable.
