We stayed as a couple (honeymoon) 4 nights at this Casa Alta small apartment on rooftop with private Jacuzzi. Overall highly recommended, and we've seen a lot of places... Good to know, this building is part of a larger hotel complex, therefore the communication with Andreas and Alexis where quite good - like hotel service (separate website of the place: casasantorini.gr FYI). Please mind, this Casa Alta place is NOT located in the main city of Fira, but in a tiny cute village 15 min drive south. We rented an ATV Quad motor, which was a great way to explore the island within maximum 40 mins drive from one side to the other. First we where a bit afraid that Santorini would be a bombardment of tourism, and to be honest it is... But we where there late June, 1 week before the high season - which probably made a slight difference. Fira was super busy / tourist bomb though... Santorini has so much to offer; the best views in the world, delicious foods, catamaran boat ride, crystal clear sea, culture >> check out the Music & Mythology Symposium just couple of houses further from Casa Alta! We also took the "Power Jet" (fast 40 mins) ferry boat to Ios, to explore some white beaches - recommend also (big waiting line at port in the sun > prepare some extra sun screen) In short, one of the best vacations ever.
