Очень хорошая школа. Инструктор Supun самый лучший. Впервые попробовала дайвинг. Инструктор все подробно объяснил. В воде за руку вёл, все показывал. Чувствовала себя комфортно и спокойно! Погружение на 8 метров прошло успешно!Posted on Dmitriy PrudtskikhTrustindex verifies that the original source of the review is Google. Очень классный коллектив! Профессиональный подход к своему делу, высокое качество за приемлемые деньги. Мы брали утреннюю рыбалку в четвертом. За 3 часа наловили около 15 кг разнообразной рыбы (фото в комментарии). Вечером того же дня нам накрыли шикарный стол и пожарили ту самую пойманную рыбу с утра, - просто пальчики оближешь.. Наблюдал как готовят посетителей к дайвинга, - индивидуальный подход и внимание к мелочам! Это очень важно. Советую всем!Posted on steffen karlstadTrustindex verifies that the original source of the review is Google. Ryddig og veldig komfortabelt! Flinke trygge dive mastere. 2 dykk uten noe klage på.
