You are in the kitchen facing towards the open arch. Turn left and walk towards the stove which is on your left side. Now slightly turn right and move towards the dining table. Walk straightly in the hallway behind the chairs till you reach the couch in the living room. Now you are standing behind the couch. Turn left and walk through the open arch. Now turn left and climb the stairs and stand in the middle of the stairs. Now you are facing the wall and there are stairs on your left side. So that will be the end point.
