Go green. One of the easiest, and most attractive things you can add to your apartment balcony is green plants. Even the tiniest balcony has room for a pot or two. Consider growing vegetables or herbs as a fresh alternative to store-bought produce.
Add seating. If your balcony is large enough, adding a chair or two will give you a place to sit and relax while enjoying your outdoor space. For tiny balconies, consider an ottoman or stool instead of a chair.
Consider carpeting. Outdoor carpets and rugs have come of age. No longer limited to that rough, green indoor/outdoor turf, outdoor rugs now come in a variety of stylish patterns and textures. For a small balcony, such rugs are surprisingly affordable and make the space feel more finished and inviting.
Use color to create a mood. Create a warm, welcoming feel on your balcony by using red, orange and yellow pillows, flower pots and other accents. Give your balcony a cool, crisp look by using blues, greens and shades of white.
Light it up. Get your small balcony a little light with candles, both large and small, as well as battery-run lanterns. The soft light will give the space a romantic feel.
