I was wondering which prive house has the best looking girls
since my trip is going to be a one off, this one time would have to be the best
which prive house has the most beautiful, young girls?

Club Bianca has an excellent reputation.

Its on Amstelveenseweg #145hs, somewhat near Ria's (push the door open, then ring bell on inner door)
Closed Sunday. If you take tramway Nr 16 from Central Station to Haarlemmermeer Station (a bus/tram) station , you are 150 yards from Club Bianca, a white cornerhouse with blinded windows.

would you say that Club Bianca is better than Princess or Yab Yum? When I was in town last, I asked the same question and was told to trry those places. I ended up going to Park 118 instead, but would have preferred going someplace that was really outstanding.
