Highly recommend this apartment, the place was HUGE. I was traveling with my parents and brother, and the space was more than enough. It was also in a great area, walking distance from the Acropolis, restaurants, bars, etc. Definitely plan to come back to this apartment my next time in Athens.
Billy checked us in and was super friendly and accommodating. He offered to keep my parents luggage until 8pm on our check out day since they had a later flight.
