We love to head in to Athens city centre. Usually on Sundays it's not too crowded. We has coffee at Zappion, strolled in Plaka, played with M in a park, chased pigeons, had pancakes at Hip Cafe, checked out an art gallery off Syntagma, discovered a new sushi place and enjoyed the sunny weather. Of course you can do all of the above in Glyfada but
Athens is so nice and has the real 'city feel' .Lovely family time indeed...
