The Greek capital - Athens - is known as the center of the ancient world. The temples attract millions of tourists every year. Although the importance of Acropolis cannot be denied, one can feel a little disappointed while looking at the few remaining monuments - there are other, off the beaten path ancient sites which are way better preserved. Go back to the first part of the article about Athens to learn about our impressions of the Acropolis - expectations versus reality.
But is it only Acropolis that is worth visiting in Athens? I've heard many saying that besides this ancient hill, there's nothing to see. Not all modern parts of Athens may be too appealing to the eye - they remind more of Middle Eastern cities (like Amman - have a look here) with houses crammed tightly between the surrounding hills. To be honest, for me, it wasn't one of the best European capitals, but it's still nice to visit and once you explore it a bit deeper, you'll find some exciting places beyond the famous Acropolis. It's possible to visit all the places described here in one day on foot.
