Closest public beach within the City. Take any tram from Sintagma Square until they reach seafront. Plenty cafes, local tavernas as well as beach chairs on the spot. Or simply throw the towel on the sand&enjoy your day. Just don't forget the sunblock)

“Originally in a mansion on "Museum Row", the Benaki has spread into adjoining buildings and has satellite museums, notably in Piraeus. Do not miss this museum, which holds collections of Modern Greek Art (post 1824).”
