Plaka is Athens' old historical neighbourhood on the slopes of the Acropolis, a labyrinth of cobbled lanes and neoclassical houses known as the 'Neighbourhood of the Gods'.
Its lanes are lined with traditional tavernas — many with live bouzouki — along Adrianou; the tiny Anafiotika enclave feels like a Cycladic island village beneath the Acropolis (https://en.wikipedia.org/wiki/Acropolis_of_Athens).
The Roman Agora and Tower of the Winds (https://en.wikipedia.org/wiki/Tower_of_the_Winds) stand at its heart; Hadrian's Library flanks the edge and the Choragic Monument of Lysicrates (https://en.wikipedia.org/wiki/Choragic_Monument_of_Lysicrates) is a Plaka landmark.
Acropolis (line 2), Monastiraki (lines 1 & 3) and Syntagma (lines 2 & 3) metros ring Plaka.
Busy, tourist-heavy and very safe; pickpocketing in dense crowds is the main caution.
