I booked Federico's apartment for my parents who went to explore Rome. They are very satisfied with their first experience with airbnb! Federico and his brother Max were really just like the airbnb community: nice and attentive to their good welcome!
The apartment is nice and clean, and very well situated in a picturesque and charming area.
Only one negative point: my parents regretted that there are no maps or no guides with advice of good restaurants!
