A Living room is like the heart of the apartment. Although some people spend more time in the Kitchen, the leaving room is the place where you need to feel comfortable. This is the reason why there is actually a lot to do with in it, mostly from the Interior designer perspective. When coming to renovating it, there isn't much to do, since it is more a container than anything else. Wallpaper is one of the things you could do, as well as play with the walls, contract a Painter, build a fireplace or change the floor.
