Besides being a diving goods shop and doing tours, they also train for diving certifications.
Last summer we took classes for open water certification. They are really great when it comes to getting people certified. But if you really want to learn Scuba diving, I would prefer not to go to them.
They rush you a lot in a lot of the diving exercises. Some of the trainers are patient up to a certain extent, but it is very clear very soon that they just want you to finish the classes and get certified.
I was not able to finish a couple of very key exercises, however they still signed off on my logs and got me certified. (Obviously when I actually went diving in the summer, I faced some serious problems).
Also, the initial training is carried out in a small pool at one of the trainer's residence and it gets very crowded to fit all those people.
Unfortunately, I cannot recommend any other dive school as of now as I don't have any experience with any other school.
