I rent a nice and silent Room (18qm) in my 3-Room-Apartment. You also can use the Living Room wich is used by me, too, the fully equipped kitchen (washing machine, dish washer, large fridge, lots of dishes, etc.) and bathroom. To the rented room belongs the flat's balcony. The Bed is extendable so that you can double the size of the bed for more space in bed.
The flat's located in the third floor. There's no elevator.
