Understatement of the century. I visited here about 7-8 years ago. The big dome pool pictured has a unique acoustic property of transferring sound from one side of the giant pool to the other. You can expect to hear the heavy breathing of amorous couples from about 20-30m away as if they were next to you. That said, aside from the inappropriateness that seems to be common nowadays in these high-end spas, it was a beautiful venue.
