Awesome space, very comfortable, and in an amazing location on Hackescher Markt. It is a 5 minute walk from museum island and many other sights in Berlin.
Eugen fails to mention a very important aspect of this place, particularly if anyone will sleep in the living room. The balcony of this apartment is about 10 meters from the train station which is extraordinarily loud. It is very surprising that he is very strict about music while there is a loud, screeching train directly off the balcony. It runs all day and night.
