We very much enjoyed our stay here! We spent 5 nights and it was excellent. The space is small, but it's very well used and we didn't have any issues. The location is perfectly situated around the corner from Campo de Fiori, and you can easily walk to just about everywhere from here (although we did take a bus places if we had a time constraint for a tour). Highly recommend this apartment and Pio as a host. And ask him for restaurant recommendations -- we tried several he recommended and they were all fantastic.
