You're facing a glass window. Turn to your right, go straight and go through the narrow passage, carry on going through that passage until you reach the exit door in front of you. Once you exit the door, you can see a portrait in front of you, beside that you can see an another narrow passage, go through that and you will see an open door, go into that room through that door and you will see a bed. Go near that, it is your end point.
