Piera's place is the perfect location for 2 people to stay in Rome. The small and very clean apartment is walking distance (10min) to the main train station, to the colosseum, to downtown with the Trevi fountain and much more. Even though it's on a main street, it faces the backside and is really quiet. Only we had a some challenge with the check-in and check-out times, but probably Italian and German sense of punctuality differ too much ;-)
