Haven't been since 2019 so I'm a bit out of date, but Goldentime FKK was top notch when I was there.
Funpalast FKK was good too. Cheaper than Goldentime, and the girls were less polite (more Romanian) but still full of stunners.

The girl you select appears in a minute or two, which is a bit of a novelty. but I've had a good time in there with some stunners.

There's the occasional german pornstar.
