Best Vacation Ever. The Deriya Deniz is a lovely gulet and our crew did everything possible to make the trip a relaxing, unique time at sea. We will never forget our captain who was all things Italiano as well as experienced and personable. Our chef created one wonderful meal after another. Our guides, Sophie and Francesca, made our experience educational, authentic, and always enjoyable. Peter Sommer was right about this being the ideal way to experience the Amalfi Coast and the islands of Ischia and Capri. Ours was an unforgettable vacation and opportunity to make new friends. The memories are vivid and unique. We will definitely travel with Peter Sommer Travels again, and look forward to more experiences like this one. Thanks to all who worked so hard to make our Italy vacation absolutely perfect. We highly recommend this tour to new and seasoned travelers.
