I spent 3 nights at Filio's apartment in Metaxourgío. The place is well furnished and comes with some luxury features -- most prominently, a 5th-floor balcony with unobstructed views to the Acropolis! It was over 30ºC outside, so the air conditioning also came handy. The location is off the tourist track but very central in Athens (I walked easily to all the touristy spots, so didn't even need a metro travelcard), and in an interesting area with some "alternative culture" feel to it (lots of grafitti, and the headquarters of Syriza are just two blocks away). Filio is a kind person who takes very good care of the flat (I would describe it as immaculately clean). To sum up, an excellent stay and a place to recommend.
