an Official Tourist Guide licensed by the Ministry of Tourism. It doesn’t get more private and personal than this, as I am not an agency. Only official guides are allowed to give tours, both inside and outside sites and museums, and we are required to wear a blue badge.

Once upon a time, Αθήνα (Athens) used to be the centre of.. everything! It was the birthplace of Democracy; home to philosophers, such as Socrates, Plato and Aristotle; it gave birth to theatre itself. There's a reason why it was called the 'School of Greece'. This is indeed where Europe and 'Western Civilization' began!
Below are my suggestions.
Of course the tours can be customised according to your needs!
