Milan is a great community, 17.9 Miles south of Ann Arbor (according to Google Map). There are several young couples and young families who live in Milan. It is a straight shot up US 23 to Ann Arbor. During non-rush hour times, it is a 15 - 20 minute drive. During rush hours, the only slow downs would be in the city, en route to or from the highway.
I've linked the Google map, which you've probably checked already.
Hope that answers your question, and best of luck to you.
