Starting off you are in a home theater room looking to the left of the L-shaped couch you can see a table in the distance and you will approach that table. When you are in front of the plastic table look left again and you will see a wooden door leading into a storage area. Look left of the wooden door and you will see an open archway into a hallway with a staircase to the right. You will go up this staircase and when you reach the center of the staircase you have reached your destination
