Your personal tour driver will pick you up and return you to your hotel in Athens, meeting you at the lobby.
In the case of an AirBnb apartment, he/she will contact you upon arrival so you can meet at the entrance of the building.
If you're arriving at the airport or port, your driver will be waiting for you at the arrival's area, holding a signboard displaying your name, making it easy for you to identify them upon your arrival.
