You are facing towards the glass window. Turn around and walk straightly in the hallway by passing the chairs on your left side till you find an open door in front of you. Walk through the door. Slightly turn left and enter the open room. Now walk straightly in the hallway by passing the washbasin on your left side and the couches on your right side till you find a closed door in front of you. Stand in front of the door. That will be the end point.
