Really enjoyed staying here. Great host, great apartment, and great location. Easy walk (25 min) to the Collesseum, and plenty of restaurants, cafes and mini-grocery stores even closer.
It's close enough to everything that you can walk, but also not right in the middle of everything so if you want a little peace and quiet you can enjoy that.
One note, it still is right over several restaurants so if you're a light sleeper, you'll hear people up until about 11pm; but nothing too disruptive...and well rather than sleep early, when in Rome, as they say.
Overall highly recommend it.
