My husband and I spent 3 days completing our open water certification at Santorini Dive Center. Our teacher, Nikos was absolutely excellent and we feel lucky that we got such a good teacher. He is a real character and very funny too, but really wants you to learn well. We are both teachers and highly rate his teaching style! Both Nikos and Pavlos ('Same Name'!!) are old school instructors who are highly experienced and passionate about diving. Can't wait to go diving again!
