I recently took a course with Kostek, and seriously, I couldn't have chosen a better place. Everything was clearly explained, the atmosphere was totally relaxed 😎, and at the same time, I felt safe and cared for. It's clear they do it from the heart, not out of obligation. ❤️ Thanks to them, I got underwater with renewed confidence and even more enthusiasm. If anyone's considering the course, don't hesitate. Go to KK, it's really worth it! ✨
