Walk forward and enter the room. Once inside, turn right and enter the door. Once you enter, turn right and walk until you reach the wall and turn left. As soon as you turn left, turn right and stop once you are facing another hallway.
Follow the hallway and turn right to enter the doorway. Then turn right again to enter the hall.
Go through the small doorway into the next room, then turn right and go through the door in front of you. In that hallway, go right and pass under the archway. Stop in between the first two black tiles on the floor.
