You start out looking down some stairs. Turn to your left and you will see stairs that go up. Go up those stairs. Then ahead of you, you will see an open door straight ahead that leads into a room with a table in it and on the left you will see an open door that opens into another room that you can't see. Go into that room that you cannot see. That is actually a hallway that you've turned into. Once you are standing in the doorway to that hallway, immediately to your left you will see a room with a white tiled floor. Go into that room with the white tiled floor. It is a bathroom and once you're facing the bathroom, you will see an open stall at the end of the bathroom. Walk straight forward into the bathroom and into that open stall and right up against the wall below that window and then you are done.
