Right now you are in a balcony facing towards the glass door, now turn slight right and enter into the glass door, which is a bedroom, now move forward towards an entrance which is in front of you, here you can see a pathway in front of you, pass through the pathway until you reach an open door which is in front of you, now pass through the door and move little bit forward, where you will find a staircase on your right and a portrait on a wall on your left, this is your end point.
