A lovely apartment in a truly fantastic location. Incredibly central, with a view of the Duomo from the kitchen. Also, we enjoyed leaning out of the window in the reception room and watching life happening in the Piazza della Repubblica below. No noise concerns at all - just the atmospheric sounds of the occasional musician in the square and general low hubbub of people milling around (it's largely a pedestrianized area - though taxis can drop you off at the apartment). Also - high up enough to feel nicely separated from it, yet able to look in. Very highly recommended.
