Right now, you're facing towards the closed door. Turn left and move towards the opened door and exit the room. Now, slightly turn left and you can see a passage in front of you. Walk in the passage until you reach a staircase on your slight left. Now, slightly turn left and walk all the way up through the stairs. After you reach the end of a staircase, you will come across an opened door. Move towards that opened door and turn left. Move forward, now turn slightly right and take a few steps, where you will be facing towards a sofa and that is the end point.
