Turn and walk down the hallway past the staircase. Continue down the hall around the corner near the potted plant. Walk up to the next open door on the wall with a bathroom inside.
Walk straight ahead, veering to the right to avoid the stairs. Go past the potted plant and into the first doorway on the left. Stop there and wait.
Walk forward staying to the right and moving towards the stairs. Turn right when you reach the stairs (don't go up or down the stairs). Go past the staircases and forwards towards the room with the double doors that have the horizontal openings. Turn left while you are still in this hallway (Don't go through the double doors). You will be just past the double doors and facing a large potted plant. You should go slightly right towards the small two paneled door that is visible to the right of the potted plant. Stop when you are just outside this room, which is a small half bath with a vessel sink.
