Drop off laundry?

I am moving soon to Washington & Sterling. Is there a laundromat in the area (Washington preferred but I can make it to Vanderbilt with my granny-cart) that people recommend for dropping off laundry? Ideally it would be open early so I can drop things off on the way to work.

Thanks!

depends on which direction you're walking (2/3 or C) but there's laundry king, a 24 hour laundromat on prospect & grand (steps off of washington), or ali laundromat on st. johns on the corner of washington.
