Chris's place was great! He even left water in the fridge for us which we really appreciated as it was 41 degrees C when we arrived to Athens!
The apartment is in a good location, with a little market not too far away. Major sites such as the acropolis or agora are not far away - you can walk within 15 minutes or take a cheap cab ride, depending on the weather.
We had a late flight and Chris arranged for us to leave our luggage with a neighbor, which made our day a lot easier. She also offered us water and called our taxi for the airport for us.
All in all, the hospitality was wonderful.
