Facing into the bathroom, turn around, head straight towards the white door in the distance with the nine window panes, bypassing the stairs on your left. Hug the left wall and walk towards the microwave in the kitchen that's elevated. Once you've reached that microwave, turn to your right. You'll now have the front door on your left, a small square window elevated to the left of a vent. Walk straight towards that elevated window and stand underneath it, you're done.
