Turn so that you are facing that open doorway. Walk towards it. You go down a couple steps to get to the doorway. Step inside. Turn left. You're going to go to the stairs and go down the spiral staircase. Once you get to the bottom of the staircase, you will see a plant to your left. You are going to jump over that plant and end standing next to the plant, and then you see into the kitchen, and then you see the dining room table and then the big open living space, and you're done.
