This was our second time using Christina, first time was just my wife and I this time we had a multigenerational group with my parents and younger children. Our first experience was amazing and she recommended book series that turned our 10 year old American son into a lover of Greek mythology. This excursion was the highlight of his 18 day European vacation. We were only in Athens one day this trip on a Disney cruise. Highly recommend Christina as a guide, our favorite we have used on our travels throughout the world. Her knowledge and ability to navigate the busy Athens tourist sites is unmatched. Very personable and easy to communicate with.
