Visited here for about 1.5 hours on our stay in Berlin. Could have stayed longer just we had other things planned. The staff were so friendly and so good with the kids 4 and 7. I would say that this is aimed more for younger kids. The staff were so good with the kids on the climbing wall, wizard ride and the factory. Even though none of us spoke German they tried so hard to make us feel welcome. Would definitely revisit.
