We stayed 5 days in Berlin at Bernd & Katja's apartment in November/December 2015 and had a wonderful time.
The apartment is exactly as on the pictures, nice, clean og quiet.
The location is perfect with S- and U-bahn just around the corner.
If we had any questions our host replyed us within 30minutes.
We can recommend a stay at Bernd & Katja's apartment.
