You begin facing a window, turn to your left, and behind the couches, that are in front of you, there is a opening, take a step towards that opening, and then turn to your left, you will see a narrow hallway with a painting on the right going all the way across, go down this hallway, make a left, and then once you make a left, turn into the first room that's on your left, it is a bathroom, and just stand in front of the toilet, you are done.
