For our last day in Greece, we decided to take a private, 4-hour walking/eating/drinking/history tour of Athens. It was phenomenal! Yannis Ninos was the most personable, warm, considerate, knowledgeable, professional, kind... guide we could have ever asked for. Yannis fit into our family of two adults and our two adult children (27 & 29) immediately. If you're going to Athens, you must take one of his tours. You will not be disappointed!
