Me and two other friends had a truly wonderful time at George's house. The house itself was clean, spacious and very cute! We particularly enjoyed having the balcony/terrasse for drinks at night, and were incredibly grateful for the air conditioning as caught the end of a heat wave!
The house was very central, within walking distance to a lot of Athen's major attractions, including the Acropolis/Parthenon, Plaka and more.
Communication with George was prompt and easy, and when we had an issue (that was completely our own fault!) he was quick to resolve it for us.
I would whole heartedly recommend George and his Athens apartment. If I ever come back, I will be certain to return!
