I agree with what others have written - Gianni and Simona are friendly and attentive hosts, the flat is high spec and its location could not be better for sightseeing. Note one caveat of being so centrally located though: the noise levels in the narrow streets all around get quite high on Friday and Saturday nights until really late, so better bring your earplugs -- light sleepers should think twice. I have no reservations in any other respect.
