You will start by facing in front of a wall with posters on it. Turn right take one step slightly at the foot of the bed. Take another step towards the TV with a console table underneath. From there, turn left and walk two steps down the hallway and exit this room. Turn left once again and walk down this narrow hallway and take one step towards the glass railing. Once you're facing the circular glass railing. Jump over that and walk towards the other side of that railing. Now turn right and walk down the stairs. Once you are at the foot of the stairs, turn right and take one step towards that black and white picture frame. Turn right once again and you will see a narrow opening with a closed door and now it will open for you. Walk towards the one that is narrow not the one that was closest to you earlier. Take a step inside and you will see a section where there is a large stone inside and you are done.
