We've stayed in the aparment for a week. It's location is excellent: there are a supermarket and a metro station nearby. You can reach duomo in a few minutes.
The apartmet itself is small but comfortable: you have everything you may need.
The only thing I'd wish to have there is a carpet. We've been there in December and while room was heated, the floor (ceramic) was pretty cold, especially near the entrance door which is ~1m from the bed (remember that apartment is pretty small).
