Before we went to Greece, many people remarked to us that a day in Athens is enough because it is just, well, a mess! WE were pleasantly surprised to find a very friendly, bustling city!! It is not as "dirty" as people said that it was, and we felt very safe all the time we were there. Athens will never get over the era of rapid building of ugly, modern-era buildings, and yet they are really trying to make the best of it. The people are friendly, and we just had a great time. We highly recommend a stay that enables you to feel the sense of history, feel the bustle and business, and of course, eat the Greek food at local places.
