Your tips See the Museums and of course The Acropolis! Enjoy the food and the beaches.
I have very close friends who live in Athens and I visit frequently. Seeing the city from a different perspective than a tourist has given me the opportunity to do things and to meet people that I would not have normally done or met. I am always welcomed by the Greek people and have always felt comfortable when visiting. The food is wonderful, but the one thing anyone going to Athens should do is visit the museums - especially the National Archeological Museum where the current exhibition should not be missed! - Seeking The Ancient Kallos. It is a breath taking photographic expression of the passion and vision of an American artist that reveals the beauty and significance of the contribution of Greek civilization on the world. And, the beaches are spectacular!
