You begin on a patio, turn to your right, and go in through the green double doors, there will be a reception on your left, go forward and just keep going until you get to the end, you will pass a staircase on your left, a bunch of doorways on your left, just keep going forward and you will see another entrance come up at the opposite end of the hallway, go through the double doors, out onto the patio, and you will take the last step, right before the staircase and the black railing on the staircase, you are done.
