is where i stay, they do have some odd looking old gay guys loitering in the reception, but if you can blinker that, the rooms are big, clean and sport a massive bed for bg,s.
They have no joiner fee, you take as many girls as you like back.
The security will keep thier id card and you will be telephoned in the room to check everything is ok before they leave.
Also you can book online and its right in the middle of Patpong, shopping galore..
