The Abion-Spreebogen is by no means a superior hotel. Only the breakfast deserves this name.
We had booked a maisonette suite, this is in the dark basement, a rickety staircase then leads up to the ground floor to the further "sleeping possibility". However, I would not offer this sofa bed to anyone. Metallic cross struts at thigh height between the slatted frame make it impossible to lie in a halfway bearable position. Sofa beds don't have to be so uncomfortable for decades!
The bathroom is completely worn out, wooden boards swollen, molds moldy and cheaply whitewashed with paint.

Large areas of carpets dirty, as well as cupboards and objects.

Complaints about this were shrugged off with the words that all maisonette suites were like that.

I would not recommend this hotel to anyone in this condition except for having breakfast.
