Facing the white couches and the fireplace, jump over the white couch that's in front of you that's just down a couple of stairs. Once you've jumped over the couch, you should be facing a fireplace with mirrors on both sides. Turn to the right and you'll see an arched floor to ceiling window. Jump right towards the base of that window. Standing in front of that window, staring out onto the balcony with a mirror and chest of drawers on your left and a white seat on your right, you're done.
