Really nice spot in the historic center of Milan. Recently refurbished, clean, and well taken-care-of.
The four flights of stairs to reach the flat aren't too difficult, but keep this factor in mind if you have a lot of luggage. The stairs inside the flat to reach the bed and bathroom might also be a challenge for some - however this is all spelled out pretty clearly in the description of the flat, and I thought the top-floor view of the courtyard was worth the trouble.
Nice place to stay in central Milan in a very convenient location.
