You're standing at the entrance of the door. Walk in to the entrance. To the right there are three cupboards, go towards the middle cupboard where you could see a hallway. Now walk through the hallway until you see a staircase to the right. Walk up to five steps of the staircase and turn around and get down from the staircase, after getting down from the staircase, turn right you could see a black and white circled carpet, walk towards that carpet, now slightly turn right and take a step forward towards the table, to the right there's a portrait named flip hanged to the wall. This would be your end point.
