Please double check the room that you book. The listing (as of May 2022) on airbnb can be inaccurate. I chose only private rooms and one of their rooms showed up. Then I read the description and saw that they do have private rooms as well so I booked it. It turned out to be a 6 bed shared room.
However, my stay itself was quite comfortable. The rooms were cleaned everyday that I was there. There's no kitchen space but there is a restaurant right downstairs. Met some really cool people at the hostel. The location is perfect for people new to Berlin that want to see all the sights in just a few days.
