We stayed at Altana in June 2014 with our three kids and it was the highlight of our entire trip to Greece. The rooms are fine, not great, and the bathrooms could use an upgrade, but the service provided by Cristos and Marios is like nothing we've ever experienced. They sat down and spent an hour planning every aspect of our three days in Santorini and it was well worth it. They sent us to restaurants and beaches that we never would have found on our own. I cannot rave enough about these guys. They even recommended a great neighborhood to walk around in in Athens after we left. The pool at the hotel is great and the views are amazing.
