We made the tour august 2010. We had a private guide because we were the only once there at the time. Pluto was very patient and enjoyed the trip himself, so we had a lot of fun! We had enough time to go around the city including the gardens and the acropolis - area. Traffic was no problem since the ways we took were all for pedestrians. Highly recommendable for everyone and certainly not only for well-trained adventure-freaks!
