If so, what did you think? (This is the one based in Leyton, east London, just in case there's other people/classes using the same name.)
We're considering private classes (which are quite pricey) but I'm a bit hesitant as I'm very much a science and statistics lead person (i.e. don't believe that just because something is "natural" it's necessarily the best thing for me) and it would be awful to spend the money and then hate it!
Thanks!
