We loved staying at Claudio's apartment!
I'd recommend it to anyone for a short or long stay. It was extremely convenient to walk to the university district and the center, it's right next to several bus lines, the building was nice and secure and the apartment was really comfortable with amazing views. We enjoyed the skylights as it's an attic-style apartment. There is a nice supermarket directly across the street and the neighborhood is bustling and has plenty of stores and restaurants without being too noisy. We extended our stay as long as possible after we arrived. Communication was great with Claudio's daughter, Eleanora, and she helped us extend our stay at the same rate.
There were a couple items in the apartment that were a little broken when we arrived (one of the window blinds, the handle of the pot, one lamp) but in fairness they were minor enough that we chose not to mention it until after our stay.
