I found this centre quite by chance, a lucky chance! It is located at Perissa beach, just below the cliffs, on the southern side of Santorini. It is an easy and quick access, only a few minutes away from the popular spots of the island, but also there is a mini bus transfer service from your hotel. Moreover, the view from the 9 meters fiberglass dive boat is for you to see. You can check out lava formations, marine life and a small passenger ship that sunk in the bay in the past. This center is also a member of Padi, that guarantees the best quality in equipment and service. The equipments is in a good state and sturdy. Generally, I had a good impression, no problem with anything, and the guide was very helpful. I had dived again in the past, but my sister hadn't tried before and she loved it!
