It's definitely a five star hotel. Athens is big, loud and takes some work to navigate (although we found it fascinating.) We know we paid more than we typically like on foreign trips but I intentionally booked this hotel both for convenience of location as well as the fact that it was the last leg of our trip and we wanted to be pampered a bit. We had exhausting but good days touring around Athens, but it is your typical big city and can be an assault on the senses. It was such a welcome moment of quiet and luxury to come back to the KG at the end of the day, In fact one night we showered, got wrapped up in our robes and ate take out in the room with a bottle wine. Pure decadence and the perfect ending to a long day.
Staff was helpful, friendly and accommodating. Location could not have been better. We took the Metro from the airport which was surprising easy. And you come out practically right on top of the hotel.
A lovely stay.
