You're starting in a hallway with stairs. Behind you is a little kitchenette. If you look up the stairs, there's a door on the left and a window on the right. Go up the three steps in front of you. Whenever you hit the little, short wall on the left hand side, turn into that area. it's empty. You can see two sliding glass doors at the far end of this small room. Take two step and go walk up to the handle of that sliding glass door. For reference, if you turn to your left, you'll see an unfinished bathroom. This is where you stop.
