You begin looking at two black armchairs in a hallway. Turn to your left, about ninety degrees, and proceed to the left of that hallway. There should be a door on your right, into a blue room. Step through that door and it is a blue bedroom. Proceed to the back right corner of that room, towards the shuttered side of the window, and once you're in that back right corner, right next to the part of the window with shudders, the little square part, you are done.
