You will start by standing inside the bathroom and on to your left you will see a hallway. Walk towards the hallway on to another door. Keep walking straight. Once you see a toilet across you, turn to your left and you will see another hallway with dark wooden floors. Take a step there and turn left once again. You will see a room with empty shelves and cupboards. Walk inside the room and stand in the middle of the room in front of the large empty shelves. Once you're there, that's where you stop.
