It was a great flat, we really enjoyed staying there. Ideal for couples. Location is good, you can get to the center fast. The host communicated well and fast. I would recommend it for any shorter or even longer stay in Berlin.
The only downside is that the host wanted 15 euros in cash for bed linen on top, which I believe would be no problem to provide for every guest anyway. It seemed to be an attempt to make some additional money outside of the Airbnb commission system.
