Konstantinos was great! We really loved his apartment. It is an easy walk to the train and only a few stops from the center of Athens. He met us at the train station and walked with us to the apartment so we would find it easily. He was very thorough. He provided us with a list of attractions and restaurants he recommended. He also provided us with a map and let us know that the next day we were in Athens was a national holiday. (So we went grocery shopping the day before) Konstantinos was also nice enough to meet us halfway through our stay to help us in purchasing ferry tickets since we were lost on how to do that. He is a wonderful host. I would definitely recommend him and his apartment!
