It worked out perfect. After picking up the keys, I used my 300mm to shoot the Acropolis at sunset. Woke up and walked to the top of Mt Lycabettus for sunrise photos of the Acropolis. Then hit up Carrefour and a bakery for a great breakfast at home before meeting up and giving the key back. Great experience, and sad that I only got one night before moving on. Would definitely recommend, especially to photographers.
