You'll start looking at a wall. Turn around. Exit the empty room through the open door on the far right. Enter into the next room, looks like a showroom. To your right is a tub, to your left you'll see a long table. Walk straight with the faucets to your left. You'll pass a tub on your right. Continue walking straight through the double doors until you see some stairs.Now it looks like these stairs go left and right, you're going to go up the first landing. Look left, walk up about eight steps. When  the stairs start to turn, you'll stop.
