You should consider yourself lucky to have Alexandra as your host and have a chance to share her place with her. Her little guidance note contains beyond what you need for Athens. Google is useless! You should try the fish Tavern Tselingas restaurant (restaurant number 5 in her Lunch/Dinner recommendation) for the Greek salad, Tomato and Olives salad and all kind of seafood that they have. I came there two times in a day because it was so good! I considered myself lucky to booked for Alexandra place by instinct...indeed!
