The place is amazing with great location. awesome balcony (heated in the winter) and really classic place. few things you might want to keep in mind:
The place is right in front of a train station with various lines. that's a huge plus but can be also very noise. there's no smart tv or cable t.v. bring your device and hdmi will be a smart move.
beside that, great place to stay in Berlin with great view of east part.
