“Extend your shopping adventure in the tourist area of the city center of Athens”
Visiting Stoa of Attalos is best with a guide, if you're interested in the history of the site. There are quite a few groups organized by private travel agents as well as public ones (free of charge, or very cheap) organized by the City of Athens.
Reaching the site is easier if you use public transportation (Thisseio Metro Station). Some of the ancient ruins of houses, of the Agora etc. that surround Stoa of Attalos were unveiled by the American School of Archaeology in Athens. The area was the heart of ancient city of Athens.
My advice is take a refreshment with you and try to avoid the very hot summer days if you can, as it gets quite hot and there are no shops inside the archaeological site itself.
