"Not that great"
I used to go up and down Michigan Avenue all the time on Route 200 (SMART bus route). From what I've seen, the part of Michigan Avenue that runs through Detroit would not be an area I'd want to live in. For one thing, it goes through several bad neighborhoods (as far as crime activity is concerned). There were far too many instances where I saw one or more police cars and an ambulance or two at various spots along the street. There's not very many stores other then seemingly second hand shops which I think number in the range of about two dozen. There's a few bars from what I've seen and maybe one or two adult gentleman's clubs but those aren't exactly family friendly. There's a lot of vacant stores up and down the section of Michigan Avenue that extends through Detroit too. All of them plus the few dozen empty houses I could spot all made the area appear dirty to me. There's a lot of construction that seems to go on almost year round on Michigan Avenue too. The only real good sections of Michigan Avenue run through Wayne, Westland, Dearborn Heights and Dearborn itself. I'd avoid the stretch of Michigan Avenue that runs from about 6th Street out to the city limits if at all possible. I wouldn't recommend anyone try living along this strip either. And also on a side note, don't expect to see much on the part of Michigan Avenue that runs through Inkster either. There's a run down strip mall right on the corner of Michigan Avenue and Inkster Road, maybe one or two shops, 2 gas stations, and a few questionable restaurants as well. It's not my type of road to go down at all.
