As an example, the last posted rate for the trip from Athens Airport into Athens itself is Euro 80 for four persons. While this isn't a bargain compared to ordinary Greek taxis or the bus, it's comparable to the price you'll pay for a shuttle bus in many U.S. and European cities.
The official provider of limousine services is the Federation of Limousines, which maintains an office at 6 Voukourestiou Street in Athens.
Their phone number, in Greece, is 210 323-3957; the fax is 210 323-7942.
Any Greece-based travel agent will also be able to book limousines for you, as will many hotels.
The "Official Limousine Rates" linked above are posted by the Greek National Tourist Organization; note that the base rates are for four people in a seven-seat limo. Larger groups will pay a surcharge.
