Are there quality alternatives to FKK throughout Europe?

I have travelled a lot and think the FKK are some of the best "brothels" in the world. I'm travelling to Europe later in the year and will enjoy a selection of FKKs. Some new and some I've visited before. But are there other types of establishments in Europe that might be as good for girls and facilities in Europe?

I went to a brothel called Vive in Madrid once that I would mention that I thought was good so if you know this establishment. I think along those lines. Equally I visited Pascha in Cologne and didn't think it particular good so wouldn't compare that as a comparable place.
