I was very happy with the location of the King George Hotel. There are lots of shopping and dining options near the hotel. The view of the Acropolis from the room was good, but the view of the Acropolis from the restaurant is amazing!
As others have mentioned, this hotel shares some facilities with the adjoining Hotel Grande Bretagne, so you may find it frustrating walking to the Hotel GB to go to the bar, use the pool, find the ATM machine, etc. This was not an issue for us, however.
The rooms were nice and the classical luxury decorations were nice. The rooms are becoming a bit worn, but they are still very nice. The bath gel, shampoo, and lotion in the bathrooms are made in Greece with olive oil and the size of the bath gel, shampoo, and lotion is HUGE!
The breakfast was good and the servers were all very nice in the restaurant.
This is a great hotel if you are visiting Athens.More
