Subject: Athens Hotels

Has anyone stayed at the Astor Hotel in Athens, and if so, what was your opinion ? I notice when checking on availability of hotel rooms over the internet, a number of agencies and hotels require your credit card number even before they can confirm if a room is available or not. I don't like to give my number unless I have a reservation. What does everyone think of this ?
