You begin looking at a wall next to a toilet, and a bathroom. Step through the door out into a hallway and move right in that hallway through an archway. You should take the next door on the right, once you're inside that door, continue through to the door in front of you and step on through that, and as soon as you get through that door, and there is an open door in front of you alongside a thermostat, and a closed door to your right, you're done.
