The apartment is in a great central location that is quiet. It is very handy for the underground/U-Bahn. It is light and the sitting room is comfortable. There are no complimentary items on arrival.
We had breakfast every day in the excellent 19grams cafe on the doorstep. A real highlight.
Others have mentioned that the flat does not have proper curtains, and armed with that useful feedback I took a sleeping mask which I was glad of.
The apartment is ready for some investment and TLC to bring it back up to the standard that you'd expect from looking at the photos - it's run by a company and you don't get the personal service of an AirBnB host. We asked if they could help us out with an extra blanket/duvet, and they ignored the request.
