We had a walking tour with Yannis and it was incredible!! It was just my husband and I which was great, but would be fun for a larger group as well. Yannis was incredibly intelligent and very well versed on the history of Athens, as well as current events. We got to see some of the more popular neighborhoods, but also areas that we definitely would not have seen without doing this tour. We saw beautiful street art, had Greek coffee and Greek desserts. We loved our time and it was SO worth doing. Especially with Yannis, he was so much fun to be with!!! Highly highly recommend.
