I have been to this place 4 times now, out of that it was completely dead once, some tense fun with a guy/girl couple, where in hindsight the girl was likely only performing to please her man, once the place was amazing with 3 girls there with 1 guy who were showing and playing with everyone clean, and once where there was only guys.
I think it all depends on when you arrive. The place was clean, safe, and facility was more than adequate.
I am not giving up on this place, so I will keep running head long toward Berlin.
