Right now you are on the stair case, walk to the top of the stairs, there you can find a mirror hanging on the wall, turn right and go near the frame hanged on the wall, now again turn right and keep moving forward and take left, you will find a door, enter into the room, there you can find a lamp in front of you, from that go straight and enter into the bathroom and stand in front of the sink, that will be your final destination.
