Centro cultural y sala de conciertos Rote Fabrik

The only issue I had was checking in (unless I missed something). I was unable to access the hotel entrance (door located to the right of the building) even after using the app. I walked in through the restaurant entrance and was able to find my room key in a cubby at the top of the stairs. Other than having clearer instructions with checking in, the hotel is fabulous. It's very convenient and within walking distance to bus and train stops.
