Facing down the stairs, turn 90 degrees to your left and walk down the hallway. You'll bypass a large plant on the left before you go up three stairs. Go under the archway towards two closed arch doors. Short of that, turn left and go down the left archway into a bedroom, There'll be two chairs at the foot of the bed. Walk just to the left of those chairs, between the beige chairs and the black chairs. Keep walking straight towards the beige chairs at the far end of the room past the bed. Jump over the left most beige chair and stand in between that chair and the glass door, you're done.
