You begin in a bathroom. Turn all the way around and exit the bathroom towards the stairs. You're going to swoosh right around the right side of the stairs though, down the hallway. Keep going, you should pass two brown armchairs on your right, and right after you pass those two armchairs there's an opening right with a brown bed in it. Step into that room and then step up by the bed, and finally to the window on the opposite side of the entrance. Once you are looking through that ground-level window, you're done.
