Location is great - very close to the underground and not far from the centre. Walkable from the Ostbahnhof. The flat is in the cellar of an old building and therefore slightly damp. The wifi didn't really work during our stay. The lamp in my room would flicker on and off. Hot water was available for about half of our stay, in the morning it was mostly freezing cold. So an ok flat but some issues which need fixing.
