Apartment is one block and a very short hill away from the Colosseum, Roman Forum, and Domus Aurea. Very central to the city as a whole, and right in the middle of a lot of the Ancient and Renaissance attractions. Trastevere and Vatican City are about 20-30 minutes walking.
A couple of convenient supermarkets between the BNB and most attractions, as well as some great spots for a quick breakfast, lunch, or relaxed dinner.
Unit was very quiet. Not a ton of sunlight, but I came to highly welcome this when coming in from the hot Roman sun.
