2. Clean and pick up clutter. More than anything else, you want to make sure your living room is fresh, clean and comfortable. If you have the time, do a big cleanup. Start at least a few days before to avoid stressing out, or having your guests arrive while you're still scrubbing the floor. Sweep, vacuum, dust and polish. Check behind cushions and underneath pillows. You don't want a guest to be the one to find that missing popsicle from last summer.
