Vicky (the person who checked me in) was AMAZING! AMAZING! My flights were delayed so I arrived later than expected, then to top it off, my luggage didn't arrive with me. Vicky met me late in the evening (almost 22:00) and when I told her what happened, she brought me clothing to wear until my luggage arrived. Such wonderful hosts. Also, the apartment is clean and tidy and near several wonderful restaurants. Additionally, functioning air conditioning in Athens during the summer is a must.
This was a great experience and I highly recommend them.
