We didn't get the chance to meet George, but Markos was the nicest host!
All our experience was perfectly well organized as Markos prepared all the info we needed.
The place is in a very convenient location, literally less than 5minuted from the subway station in the airport line.
As for the house, it really is the perfect place to stay! It has everything you need (even those last minute details you never remember to bring when you are traveling). The beds are amazingly comfortable, the A/C works perfectly; the wifi is super quick; the balcony is very nice.
The place was super clean!
Since the access is made by codes you can check-in at your own schedule and Markus volunteered to keep our luggage after check-out until the time of our flight.
We definitely recommend this place for your stay!
