You're on a flight of steps. Walk down the steps. All the way down, you'll see there's two doorways into the same room. Slight right onto the doorway on the right, and walk straight past the bathtub on your left, and the exhibits on the white columns on the right, and the banquet table with the artifacts on the left. Continue walking straight towards the other end of the room, and take a right into this empty room. Once you're inside, continue walking straight into the top right corner. If you look behind you, you should be able to look directly through the open door. That's where you should be standing. If you're looking at the exit, inside this room, to your left should be a closed door. You want to be in that corner. You're done.
