unfortunately very bad experience! After booking online with some difficulty (the website is partly incomprehensible) and paying €26, I go to the appointment. I notice that it is a collective free body course (the machines are used as carpets). The attendant immediately explains to me, a little embarrassed, that I would only be on the "Waiting list" and could only participate if one of those booked does not arrive. . In fact, after 5 minutes he bids me farewell with "I'm sorry, everyone has arrived"!
