You're facing a curtain. Turn to your extreme right and go straight, take a right turn and go near the mirror and enter into the room which is beside the first mirror. Take left and go near the staircase and go forward beside the staircase and take a right turn and go straight, again take a left turn at the first arch and now take right at the first door and go straight until you see a glass window in front of you. Stop near the door, it is your destination.
