I'm going to Michigan next year but live and work in Detroit right now, right around Wayne's campus. You have nothing to be worried about in and around Greater Downtown Detroit (which includes Wayne's campus, Midtown, Downtown, Corktown, the Riverfront, Woodbridge, New Center, and the Villages). Detroit is an amazing city with a lot to offer. Some of the neighborhoods are pretty rough outside of what I mentioned, but the part of Detroit you'll be living is very young and thriving.
