We loved the apartment, the area, and our stay there.
Thoroughly modern, with high quality workmanship throughout. The few unfinished light sockets and what not (the apartment is on the second floor of what appears to be a brand new little house) fit nicely with the raw concrete walls and heated, massive wood flooring.
The area is like a little old village that has been incorporated into the big city without loosing its village feel (it even has its own, pretty modern, local pub/restaurant/... in the form of Fuchs und Fiedler, well worth a visit). Perfectly quiet at night, and when we visited in December, the morning sun was streaming through our windows at about 10 am.
Wish we could have stayed longer, and if we knew how much we would like it, we would have.
