As you’re entering the adult world, you need to be able to do your laundry!
If you are lucky then your residence will be equipped with a washing machine and tumble dryer. However it is very possible that you will need to organise these services yourself. You have three choices here, either: purchase a washing machine, rent one, or take your washing to the nearest laundrette (wasserette).
In the majority of student homes, there will already be a washing machine. It is common that the cost is shared amongst all the students in the house.
