Washer and Dryer
Washer and dryer are in Building B (the back one) in the basement (-1).
Washers cost 3€ (where to get change for machines) and dryers 2€ per load. Money for the washers goes into the left slot, dryers into the right one. Don't mix those up, the system does not return paid money (which is shit, but that's the system).
The two rightmost washers need laundry detergent. It goes into the lower right slot. Don't overfill it, please. If you have tabs, put them directly in the wash, since these tend to clog the system.
The leftmost washer costs €3.50 but has detergent built in.
