You begin looking up a couple of steps down a hallway with a wooden floor. Turn around completely and move down the stairs with the iron railings. You're going to go all the way down the stairs and and then make an immediate right turn into a little sub-hallway. Go down that hallway, you'll step down two steps, and you will stop right before a bedroom. In the middle of that bedroom door and a dark bathroom to your right. Once you're between those two doors, you're done.
