Never experienced such a nice gym. The lesson has a clear structure, there is a lot of personal guidance and the atmosphere is relaxed and informal, so that you can go to the teachers or other higher graders with all your questions. They are very competent and explain everything clearly and patiently, even if you ask several times. In addition, you learn something new every lesson and a lot of attention is paid to your technique. I recommend everyone to come and take a trial lesson!
