Go down the stairs, and walk straight. Enter the living room on the other side of the hall. Go down the stairs, and stop.
Walk forward, with the stairs behind you toward the doorway with two frames on either side. Go down the three stairs to the landing, then down three stairs more and stop at the bottom, in the entrance to a room with a grand piano.
Go straight and down the steps until you get to the white couches and the fireplace. Wait there right before you reach the couches.
