We stayed at Werner's beautiful apartment for a few nights in September. We were three couples, and the apartment suited us perfectly as it is HUGE (much bigger than the pictures depict!) and it gave us plenty of room to both have our own space, and be able to share lots of time in the communal dining and living areas.

We would highly recommend it as a cosy, homely, spacious place that really feels like a home away from home! All six of us were delighted with our stay.
The location is pretty well-connected, too. A short walk to two u-bahn lines and relatively quiet (although there is like double glazing on the windows so you can't hear anything anyway).
Would definitely stay here again next time we're in town! Thanks Werner :)
