Turn around and walk to the right of the grey couch. Wait at the top of the stairs ahead.
Turn until the two black couches that are facing each other are directly in front of you. Then go through the exit to the room that's on the opposite wall from you and that requires you to take three steps upwards and has a pair of pocket doors to allow the room to be closed off. After you've passed through the opening, stop.
walk past the couches in the living room to the hallway.
