"Rooms are comfortable and clean, and nice roof top pool. The light shining through the transparent glass wall in the shower does little for anyone trying to sleep in while their another occupant is up and using the shower/bathroom. There is no Netflix, etc. and using a HDMI cable did not work to attach a computer/tablet to watch movies. Only 2-3 TV channels in English. If the hotel has a conference, the elevators are over filled, especially in the morning, trying to get to the roof top breakfast area. There is no other location in the hotel for breakfast. Took almost 15 minutes to get a elevator car down to the lobby to check-out. No free morning coffee available. Metro station 15 minute walk. Overall, not a "Grand Hyatt" experience at all. Find a small hotel closer to the Acropolis main area to really experience Athens!"
