In a small apartment, all that is required in the living room is a couch, chair and coffee table. You may want to place a tiny bookshelf in a spot to hold books, and mags with small light on top. Keep furnishings against the wall so the floor space in the heart of the room is wide open and easy to walk through. A colorful accent rug in this area adds texture and extra color.
The bedroom may be small as well; provide it with a twin or full size foundation, a nightstand and chest of drawers. Keep mess in this room to the very least as well, and add color with large wall hangings.
When decorating small rooms, you should keep chaos to the very least. Display just a few brightly colored accents and accessories to add depth and interest. Inside the living room, a single large vase filled with fresh flowers, a sizable candle and a single printing or painting using one wall are all you need to add color while keeping the region wide open and spacious.
