I had a incredible experience with Ocean Sound in Koh Tao doing my AOW certification! I was looking for something beyond a dive center with a party hostel and thankfully found this place that professionally blends two activities I like, yoga and diving. Ocean Sound staff was always kind, polite, and had a very professional approach on all their activities. Thanks Jasper, Zuz, Fede, Iris, Ko and everyone working on the boat for making of this, an excepcional experience.
