Simply put, Haidi's place is perfect. Its right next to the Acropolis station, right down the street from one of the Acropolis entrances, it has great restaurants around it (go to Smile and say hi to Zoey and her mother Conny). The apartment is modern, everything works, and is very well taken care of. Haidi is just an amazing host. No matter if I messaged in the morning or evening or any time in between, the responses were almost immediate. If your looking for a place to stay while exploring Athens, I can't say enough good things about his place.
