Walk away from the bookshelf. Enter the next room and walk through it, toward the staircase. Start up the stairs and stop about two steps up.
Go straight and pass the table and go straight into the other room. Go straight and pass the couch and go into the other room and go up the stair to the second step.
Leave the dining room, go through the entryway, walk through the living room, and wait at the bottom of the stairs.
