Now turn slightly left and walk straight, you will reach a room with bed inside it. Enter into that room. To your left side you see one open door. Turn left and exit the bedroom and walk towards the stairs. Climb down the stairs and go straight to the opposite stairs in front of you. Once you climb up those stairs you see a close door in front of you. Walk towards that close door. Sorry open door you find stairs in front of you. climb two steps and stop. That is the end point.
