Planned on taking the metro train to the Plaka but was approached by taxi driver who said he'll take us on a tour of Athens for 30 euros each for me and my friend. We took him up on his offer.
I liked it. Took the bus into town. Then purchased a ticket to walk the old town wall.
Purchased ticket to ride cable car up the cliff. Took the bus to Oia. Very beautiful. Walked down the cliff. It was hot and smelly from all the horse/donkey dung. Nice experience though.
