I found the place.
What I have done was:
- list all subway stops in Berlin (177), thank you once again, the-asca: https://forum.openstreetmap.org/viewtopic.php?id=71632
- using Google Street View API download two pictures (heading 0, heading 180) for each subway stop (bash script for Windows WSL, curl, output .jpg)
- look at the pictures (not all were available), write down filenames of places similar to the place I was looking for
- go to Google Street View and look at all remaining places (21)
The place is in Britz near U7 subway stop Blaschkoallee:
