My husband and I stayed at Heinrich's for a couple days. The apartment was just as described and as photographed. We liked the set-up of the living room with median separating the bed. Also the place stayed very cool during the day, despite warm weather outside (with curtains closed). It was also great to be next to the Tempelhofer Field. We ran and/or did yoga in the old airfield, now park everyday when we were in town.
It was a little bit noisy at night with the courtyard outside the bedroom window and somewhat thin walls. It didn't bother us really, but I'd suggest earplugs for those who are more sensitive.
