Had a wonderful time here with 5 people. The space was modern, clean, well-equipped, and fully stocked with kitchen supplies. They even provided us with a delicious breakfast spread for our entire stay.
Everything was very professional and well-managed. The host answered all questions promptly and arranged airport shuttles for us on last-minute notice.
Location is also good, situated within walking distance to all the main Athens sites. You can even see the Temple of Zeus from the balcony. Would highly recommend.
