Any recommendations on where to stay in Santorini, Myconos and Athens? My husband and I will be staying in Santorini for 4 nights, Myconos for 3 nights and Athens for 2 nights. We would like to stay on the beach. We have heard the beaches are beautiful but we are not sure which hotels are on the beach. We would like to stay at a hotel that is four stars and above. Any suggestion would be greatly appreciated. Thanks!
