The Altana is probably one of the premier locations on Santorini. First rate in every way I can think of (service, staff, comfort, design, pools, etc.), but the fact that it is perched above everyone else, in what is probably the best spot on the Island, with views of the indescribably beautiful sunset (save yourself the trip to Oia, just watch it from the Altana pool deck) make it THE place to be in Santorini. Can't rave about it enough.
