Marcos Rooms was a wonderful place to stay in Santorini! It was practically in the heart of town, which gave us easy access to restaurants, shopping, and the major bus stop (which also had the tourist information booth). The rooms were clean and spacious, and the free breakfast they provided in the morning was lovely (all questions and requests we had were met). The only minor challenges were the room got very cold at night (though I attribute that more to the season we were visiting the island than the building), and the matresses were decently hard. However these minor things in no way would keep us from staying at Marcos Rooms again, just something to take note of it you are a person who needs specific sleeping conditions.
