It was very cool being so close to the Duomo because everything is close and its easy to get back to (just walk toward the Duomo!). The apartment was fine, we didn't cook anything but there were plenty of kitchen utilities and coffee for one morning.
It was very quite in the apartment, we were always surprised when we walked downstairs and out to the street that it was so busy - we heard absolutely nothing upstairs, which was extremely nice.
Great locks on the doors and a gate to get into the main area with the stairs, so it felt tucked away and secure even though there is a lot of street traffic.
