I have been attending Claudio's lessons for about 2 years. He is a great professional, serious and attentive, but also nice! The lesson always has no more than 5/6 people, who are therefore followed with care, the environment is very pleasant and relaxed, never exaggerated, and the lessons are appropriately intense and calibrated. And even though my job means I'm always on the go right now, I still try to never skip my weekly class!
