I came to Hamburg to see a show/concert at Die Fabrik and decided to stay here because it was reasonably close to the venue. The bottom line is that the hotel is a cool, quirky spot that provides a clean and quiet room for travelers where everything, e.g. wireless, works as it should.
Located conveniently on a bus line, but not close to a subway/train, the building looks as if it was originally a generic space that the staff creatively turned into a funky design for the hotel. It is in a decent neighborhood (just down from a police station), about a 7-10 minute walk to shops, stores and cafes. Most important, the hotel is characterized by a very hospitable staff. Felix, in particular, was a very nice/helpful guy. I did not have the breakfast, but saw that it looked good. I also noticed that they have drinks and snacks for sale that you can bring to your room.
Not a luxury destination meant to pamper you, this is a reasonably priced place that delivers on comfort and cleanliness and does it in a fun way to make your stay pleasant. I would recommend it to anyone going to Hamburg who does not mind being reasonably outside the major destination areas and prioritizes those attributes.
