You begin in a washroom, in front of you, there is a doorway, exit the washroom through that doorway, and then go out into the walkway on the right, you will see a staircase on the left, take 2 steps down the staircase, and then look up, next to the portraits of the little girls, there is a doorway, hop over the stairwell and the banister towards that doorway, and you will enter a patio, stand in the very middle of the patio, and you're done.
