You are going to start facing a tv , a lamp and a mirror. Turn right an take two steps to go outside that bedroom. Turn slightly right and step on the wooden floor ahead of you. Turn slightly right again and step on the green rug. Turn left and you should see a staircase going down. Go down the staircase. Once you get to the bottom, turn left and take two steps to get to the light brown cabinet/bookshelf ahead of you, after the fireplace. Once you are next to the cabinet, facing a bunch of books, you are done.
