I would think it is an FKK club, but it could be a brothel. The only difference is the women are all wearing something. They don't mention prices of the women but they do mention the 50 Euro entry. The problem you might have is since its remote they might not speak much English so prepare yourself for this. Most big clubs have women that speak English or English guests so they're prepared for you. If you get one of these hard core German speaking women that don't want to deal with you, prepare for it. Good Luck
