I highly recommend Eudaimonia for tours in Greece. Nikos and his company did an AMAZING job of planning our airport transfer, three-day tour down the Peloponnese peninsula, and a day tour of Athens. I contacted Nikos about a week before arriving in Greece, and he responded quickly and was easy to communicate with. He was able to confirm our tours and airport transport instantly.
Nikos uses very clean and new cars and booked us in a fantastic guesthouse amid an olive farm with a private beach in the back. What made this tour so enjoyable was Nikos himself. He drove us to the sites, provided great information about the sites, and is a very interesting person to speak with. Nikos even took the time to take us to a market to buy Greek olive oil we wanted to buy. The places he took us to for lunch were amazing! In fact, we went back for dinner at these places because they were so good and authentic.
I travel a lot, and Eudaimonia is one of the best tour companies I have experienced. Nikos and his team really take pride in their work. I give Eudaimonia my highest recommendation.
