I'll be visiting to Berlin in September. I've been there many times and know the city well, but this will be my first oppportunity to try the FKK clubs. I know that Atemis is the recommended bordello, but I'm also interested in the flatrate partytreff/gangbang places. Is anyone familiar with Erlebniswohnung, or can you recommend a similar place?

Please don't PM. I don't have VIP at the moment. Thanks.
