The location of this apartment is amazing. It's not too far from all the major sights by walking. I would highly recommend taking the taxi to the apartment from the train station rather than fighting through the crowds around the Duomo. That was a bit of a hike. Marella helped us with restaurant reservations and her friend checked us in. The only gripe I had was that the bathroom was a lot smaller than we had anticipated and there wasn't a lot of ventilation. Other than that, the location is perfect and it wasn't loud at all. In fact, it was nice to hear church bells throughout the day.
