I did at the DLH (we stayed there). They have a decent sized laundry room, but the washers are a bit small.
One tip I have - if you have any sample sized detergents in little foil packages, pack those. I had a couple and packed them. Then you don't have to buy any, and the packaging takes up very little room. Oh - and bring quarters! I suspect most places have change machines, but I always have bad luck with those.
