Apartment was clean and right next to the Duomo as well as centrally located to all of the tourist sites. We didn’t take a single taxi except to and from the train station.
The host was extremely helpful as we arrived before our checkin. She arranged for us to be able to drop our bags and “check in” early and get the keys before going out.
As previous reviews have noted, it does get a little loud, but the noise nearly completely died down around 1130 and midnight.
