Costanza is simply a wonderful host -- I'd stay here again without hesitation. Her apartment is located in an authentic Roman neighborhood away from the tourist traps, yet an easy bus or metro ride from the classic sights. The guest room is spacious, clean, and quiet, with an extremely comfortable bed—by far the best I'd slept on in two weeks of traveling. Finding coffee and breakfast ready in the morning was another nice touch. I really enjoyed chatting with Costanza (and picking up some Italian vocabulary). A great experience all around.
