With the bed behind you, walk through the doorway to the open area on the right. Walk towards the pool outside and walk along the right side of it. Go back inside and stand behind the one closed door/window on the right side of the pool.
Go through the entryway on the right and then go through the large outside window. Stop next to the rock slab.
Go down the hallway from the bedroom and enter the opening on the right towards the living room. Go through it and stop at the fat marble wall with the sliding door to the pool.
