The Ballhouse hostel has a 1920s atmosphere and is connected to the main building. In the entrance there is a very old berlin pub with an amazing ambient. The Biergarten, or terrace is perfect for leisure time. If someone also wants to go out there is a club/bar again directly at the hostel. All in all everyone is very nice and has a very cool attitude. I would recommend it 100%. Nice uncomplicated and the facilities are also quite new!
