Marco was a wonderful host. He was flexible with our arrival time, coming in from an international flight, and prompt with his responses in helping us figure out the best way to reach the apartment.
As other reviewers have said, yes it is small - in a charming courtyard building, but it has everything you need and the location is great. Steps from the Duomo and very easy to get to from Milano Centrale via the subway. We were easily able to explore the sites and restaurants of Milan from the apartment - highly recommend!
