Walk past the front door and the big chandelier and walk straight through the doorway on the opposite side from where you started. Keep going straight down the hallway until you are standing under a hanging light in front of three paintings hung vertically.
Turn around and enter the foyer area. Walk straight across and through the doorway. Walk all the way to the end and stop in front of the paintings at the end.
Go straight into the room with the front door and continue straight through the archway, continue to the end of the hall near the three pictures and stop.
