Great location with a clean room and everything you need with a separate work/dining area and little kitchenette. Windows and balcony have a great view of Berlin from the upper floors. Responsive communication via WhatsApp at all hours.
I like that they have a restaurant/cafe downstairs and also an outdoor workout area with some weights & kettlebells. There is also a laundry room but, but only 1 washer and 1 dryer which weren't working half the time I was there. They do provide detergent though!
Overall a good experience, I'd stay here again!
