The machines were clean and easy to use. There were a lot of dryer sheets all around on the floor and no attendant/employee at all. When no attendant is there, the bathroom is locked - had to go next door to Huron Market. I did not find any single-load washers, just double ($2.50) and triple ($3.75).
Overheard another customer explain that you must put 75 cents in the dryer for 21 minutes. If you wait to check the load after the dryer stops, you must put 75 cents in to start it up again. If you check it before it stops, you can add just 25 cents for additional 7 minutes. There should be a sign posted about how the dryers work.
I was there from 11:15 - 1:15 on a Friday afternoon.
