Federica and Jacobo, as well as their flat, were fantastic! You couldn't ask for a better location: within an approximately 10 minute walk to just about everything most tourists come to see. Our hosts were unbelievably accomodating, responsive, and informative. Their handy list of restaurant recommendations was invaluable, but I'd definitely add one more stop: Gelateria La Carraia. We went there 3 times in one day! Anyway, thanks again, Federica and Jacobo!!
