My boyfriend and I had an absolutely incredible time at Hotel Kallisto in April 2025! It exceeded our expectations in every possible way, and we wish we had stayed for longer than 3 nights to soak it up even more. Our stay was the highlight of our 16-day vacation. The service was outstanding! Even before arrival, there was clear and helpful communication from Antonio and Adele. Then on arrival, Adele gave us a wonderful orientation to Santorini along with personalized suggestions for our itinerary. Adele set up all of our organized activities (car rental for us to explore the south of the island, a great small group sailing cruise with awesome captains Antonio and Yorgos through the caldera) and transfers (hotel to ferry port). She coordinated all of this perfectly which entirely removed any stress we could have felt around arranging travel logistics. Adele's enthusiasm coupled with her wealth of knowledge and local connections is an incredible asset, even for savvy and experienced travelers who research! We were blown away by how warm, welcoming, and helpful all of the staff was, including the kind breakfast hostess and housekeepers. The positive energy and reliability of all at Hotel Kallisto greatly enhanced our relaxation and enjoyment of our vacation. Regarding the amenities and facilities, everything was somehow even nicer than the photos capture. The view is spectacular and truly unbeatable (I researched many lodging options on Santorini and walked by most during our trip out of curiosity--Hotel Kallisto has the best view, a large pool by Santorini standards, AND an ideal location). Breakfast was exceptional, a perfect balance of being tasty and filling, also feeling luxurious without being too upscale or over the top to make us uncomfortable eating in our pijamas. Our maisonette room was much larger than we expected, everything was functional and comfortable, and we loved being right near the pool and at the highest point for the gorgeous caldera views!
