The apartment was comfortable, modern and clean and had everything we needed for our overnight visit to Milan. Its location was perfect for us because we wanted to be near the Centrale train station, yet in a quiet street, and the street it was on, though right near the station, was residential and actually very quiet, so we were able to get a very good night's sleep before our long journey to the airport and back to the US. The apartment's location was also a comfortable, somewhat longer walk to the main sights in town -- the Duomo, Galleria, etc. Overall, we were totally comfortable in the apartment.
One note -- the situation with the locks and doors leading to the apartment is a little complicated, so we'd suggest making sure that the explanation of which key to use for which lock is clear to you. Marcello, who greeted us, was very helpful and cordial, and we appreciated his helping us out promptly with a slight problem we had with the keys, which turned out to be easily cleared up. All in all it was a pleasant, convenient place to stay and we would very much recommend it.
