Very nice apartment, very good location - most important places (eg Colosseum, train station, shopping street) are within walking distance. If you don't want to walk, you can take a bus . Franco is a very good host, he really wants that the guests to feel good. The street may be a bit noisy, but - Rome is a big city, not a village, so it's normal. In any case, the sounds from us on the street did not interfere with enjoying a peaceful sleep.
