You begin at the foot of two bed, looking in between them. Turn to your left and exit the bedroom through the open wooden door into a bathroom. Continue directly through the bathroom, through the door on the opposite side, towards another bed. Move towards the trunk at the foot of that bed and then turn left, and move to the head of the stairs. Move all the way down the stairs and once you get to the very bottom, you're going to turn slightly right and step up to the glass doors. Once you're on the left side near the glass doors, with lots of little window pains, lots of little squares, you are done.
