With your back to the bathroom, take a step into the hallway, towards the white closet door. In front of you there are two rooms that look they have beds in them. On your right there is a stairwell. Go up the stairwell. At the top of the stairwell you are going to, you are going to that entrance to your right, to that empty room with that open window. Walk to the edge of the window you can see and stop in front of it. Walk back to the door you just walked through and stand in front of it. You are now. Take a step forward so you are standing right in front of the stairwell. On your left there is an opening. Stand in that doorway. You will be looking into a bathroom but your final destination is that entryway to the bathroom.
