You begin looking into a living room. You're going to move just a little bit to the left and through that door on the left of the inset shelf. Once you're through that door, you're going to go to the first entry on the left. That's literally straight through that door, there's another door on the left hand wall that leads to a bathroom. Step forward up to the sink and then take a right and step in front of the toilet. Once you are in front of the toilet, looking at the weird optical illusion painting, you're done.
