If you are thinking of hiring a private tour company in Athens, my husband and I highly recommend a company called Private Greece Tours. The owner, Nikos Loukas can be reached via email at: email@example.com We initially found this company last year and I was a little hesitant giving my credit card number because I had no idea who we were dealing with. Let me assure you, you have NO WORRIES!! Nikos does not charge anything to the card and you pay cash after the tour is over. They are a professional, knowledgeable, trustworthy company that I would highly recommend to anyone. What I like is that you can either tell the company what you want and they will accommodate, or, you can ask them to plan a tour for you and they will build it around your wants. The owner, Nikos Loukas, takes a personal interest in each of his bookings and tries to come and meet the clients as they tour with their driver. This May we took a second tour with Nikos’s company in Athens, with the same great driver we had last year, Alex (the Great!!). By this second tour, we really felt we were meeting a friend, certainly we were treated that way. This trip we were accompanied by our daughter and son-in-law. Alex knew exactly the best agenda to suggest, we had a great day, and the kids loved it. He timed our tour so that we got to see first hand the changing of the guards, which was a real highlight for us. He took us to a point in Athens that provided the best city look-out point with a breathtaking view of the city. We feel we have two true friends now in Athens, Nikos and Alex.
