You are facing some hieroglyphics on the wall. Turn left and take two steps up the stairs and go straight into the room that is the second door on your left. It is right before you get to the radiator in the hall. Go into the dinning room area and when you get to the table turn right and walk straight to the first window as if you are gong to be in the corner... actually you are just going to be on the carpet before the window. You are done.
