This is a spacious & tidy studio apartment conveniently situated a few metres from a pretty central metro station, so only minutes away from the Acropolis and many central sites. Kolonaki district, and Lycabettus hill, are really close to walk to.
Be aware that the apartment is on a 7-lane road, so the road noise is significant, and present almost continuously; that's the price of being so conveniently close to this metro station.
Air conditioning works well, and quietly, and the price was very reasonable for this nice apartment.
