Highly recommended!
Katarina's place is lovely, and had everything we needed.
It was clean and bright, and very well situated, a couple of minutes from Potsdamer Place and the Jewish memorial.
There are lots of restaurants, shops and bars very near by. But it wasn't noisy.
Katarina's communication was excellent and very fast.
She helped me arrange a last minute late check in because my flight was delayed. And helped me get some things back which i left in a drawer.
There is a useful Berlin guide book in the flat.
The building work was minimal - laying a pavement outside the next door building. There was some noise between about 8am and 9am as they used a digger to lift the old slabs. It looked as though this work would be completed very soon.
All in all a very enjoyable stay. Thank you.
