Traditionally, fireplaces were considered to be the ideal central element into a living room, but in modern homes, this is unlikely to be possible because of space limitations! But it's important to remember that the intention of your living room is to be inviting to people, to get them to feel comfortable and relaxed, and stimulate good conversation. So even without a central fireplace, making the fireplace some sort of focal point will also work well. Mirrors are a wonderful tool to enhance Feng Shui in a living room. They bring light into darker areas and will reflect aspects of the bedroom that visitors may not otherwise enjoy. Mirrors make rooms look larger (and lighter) and very usefully, they can reflect the door, so any seating that cannot face the door can still have the door visible through the use of mirrors. Again, we need to adapt this principle to modern cities and homes, even though the best placement for a mirror is the place where it can reflect an attractive view.
