Good value, very clean, great location A review of King George A Luxury Collection Hotel
Unlike some other reviewers I found the hotel to be excellent value, at US$220xnight, with the best possible location and in general clean and in excellent condition after extensive renovations (something you can't take for granted in Europe!).
The breakfast buffet is expensive and limited, but dinner or drinks on the roof-top terrace in front of acropolis is truly priceless. The Maitre´D is snobbish and should be changed, but the food and service is of a high standard.
The concierge was very helpful to us and arranged all our requests (dinner reservations, private tours and guides, shopping recomendations, etc.) quickly and professionally, I even saw him manage to recover some other guests lost camera from a cafe on one of the islands and have it brought to athens overnight (thats a feat in greece!).
I wouldn´t hesitate to recomend this hotel to anyone going to athens, just make sure to get a good rate :)
