Don't hesitate to book this place! You cannot beat this location. You step out of the building and the Duomo is a few steps away. Not to mention the terrace and the view. Joanna brought us the keys, she was lovely!
Location - stunning and close to everything
Terrace - private area (but part of a shared space though)
Air conditioning gets really cold in the bedroom (it's really loud, but it works like a white noise machine)
Kitchen - has everything you need (grocery stores are close by too)
Elevator - doesn't go to the top floor, you will need to carry your suitcases up 15-20 steps (just so you're aware)
Wifi - signal was weak, we ended up using our own data most of the time
Quiet despite the busy area
Bed was comfortable
Washroom - clean, lots of hot water available
We stayed for a week and felt like home. We would definitely stay here again.
