Although that I am Cypriot I hardly remember Athens small streets.
I took the metro from Elliniko to Sintagma ( red line) and I change to Sintagma ( which is the parliament of Greece and Ermou street in that area) I went to Monastiraki and I found the small streets as the photos shows below.
The I went to sintagma to see ” Tsoliades” in front of Parliament and feed the birds. I cross the road and down hill is Ermou Street with all the shops. At the end there is church as you see the photo below
