Having been continuously inhabited for at least 5,000 years, Athens is one of the oldest cities in the world. I hate to be a Debbie downer – but this was not my favorite city of my Euro trip. Sure there are breathtaking historical landmarks and mouthwatering morsels – but it was covered in graffiti and the heat made being surrounded by concrete feel like summertime in New York. If you plan on visiting Greece, I recommend just staying one day in Athens and knocking out everything you can. Daily makeup was at a minimum and I never left our Airbnb sans Tarte travel facial mist.
