We had some wonderful dives with guides Daan and Mira from Goodtime Adventures. Relaxed diving from their own boat, followed by drinks and snacks at their lovely, cozy beach bar. The crew always brings such a great vibe. We truly enjoyed it. Best regards!
I did my open water cert with Goodtime and it was exactly what I was looking for. From the moment I arrived, all the instructors and divemasters were genuinely nice and friendly, and really the only way I can describe the experience is relaxed and welcoming. My instructor was Daan and he found a great balance between being strict where necessary and approachable. He's a fantastic teacher, both in the water and for the theory. He explains things in a way that's easy to follow and he can tell when something doesn't land. I can't recommend this dive school enough. If you're unsure, just come by and talk to them and you'll see what I mean. edit: I also did my advanced cert with Goodtime, that time with Ana as an instructor and I had an amazing time, I also did some fun dives with Lucas who's a fantastic diver a genuinely such a nice person above water too. All these people are amazing instructors and I'm so grateful for my time here. Hope I get a chance to come back and dive with you guys again :)
Great experience completing my Open Water course with this diving centre. A special thank you to instructor Ana, who was incredibly supportive and helped us stay calm and confident throughout the training. Highly recommended!
Super fun experience, definitely recommend! As a first time diver, Lydia was awesome and really made sure I felt in control and safe ☺️
Had two dives with Lydia today and she was an absolute legend. V happy with the experience and can’t wait to come back 🍻
A truly wonderful diving experience, despite the poor visibility. Mira, our divemaster, provided excellent guidance and support. Absolutely no complaints, go for it without hesitation.
