The hotel was lovely and the room was what we expected. It was extremely hot while we were in Berlin and as we were on the fourth floor the window understandably had a stopper so we couldn’t open it too far. unfortunately this meant the room could not cool down and whilst we had a fan the lack of air flow was extremely unpleasant. however this was not the fault of the hotel per se, just something to be aware of if you are visiting in the summer.
