The apartment is small and partly underground, so it can feel slightly claustrophobic. For us this was good, because it meant a cooler temperature than outside as it never received too much heat! The best part about it is the location. It's amazing, really close to everything and surrounded by restaurants, cafes and anything you may need. Tram station and metro station right outside! Acropolis and Agora are only about 15min walking, so is the Panathenaic Stadium. And everything is reachable by metro too, which is really cheap! The private driver service is excellent, very nice drivers and easy transfer, and the price is fair compared to the normal taxi fares.
