I am renting out my room in a Student Dorm because I am leaving earlier. That means you will have your own room with desk, lamp, closet, bed, shelves, drawers. You will share a huge kitchen and our four bathrooms.
The place is near the lake Schlachtensee, so it is perfect if you want to spend time surrounded by nature and take long walks or doing sports. Moreover the place is just 50 min from Mitte, so you can visit Berlin during the day.
