I enjoyed staying in the apartment very much. The location is great, very close to the Duomo. The street itself is quiet. The apartment is modern, spacious and well equipped. Only the kitchen was a bit low for me (I'm quite tall). There is no lift, so you need to be willing to walk some stairs, but, except for the first time with the suitcase, I did not mind.
If I visit Milan again I will definitely try to book the apartment again.
