You will start by standing at the top of the stairs. Turn to your left and walk down the stairs. Once you're at the foot of the stairs turn to you right and you will see a black and white picture frame on the wall. Walk towards that. Turn right once again and you will see two openings. Walk towards the opening that is farthest from you and is also a lot smaller than the one next to you. Once you are there, go inside taking two steps. You will see a mirror on your right and a stone. Not sure what that is but it's a stone. Once you're here, you're done.
