And, in addition to your second question: no, it is not self-service. The hospitaleros will put the laundry in the machine. It takes only 18 minutes, so maybe you can wait (if it is not too busy when much laundry is already waiting to be washed). You can ask the hospitaleros.
After the washing you can hang it at the washing lines outside the albergue or, if it rains, on the clothes racks inside the building. In that case: keep in mind the door will be closed at 10pm! We open the door in the morning at 6am.
