I've been taking group Pilates classes with Britt since late last year. Britt explains all the exercises in great detail, corrects me if I do something wrong (and if I don't understand something in German, she is always ready to switch to English for me, which I hugely appreciate!) As a beginner in Pilates it was very helpful for me to take a few individual classes to sort out technique and breathing, and then do group classes more efficiently - I highly recommend it. I really like the lovely, illuminated spacious studio, but I suggest you come there already in sportswear, because there are no special changing rooms.
