Latin/Ballroom dance classes in Amsterdam

Hello everyone,
I intend to start some dance classes (I am interested in latin and ballroom) in Amsterdam soon. Can anyone recommend some good ones ? And by latin I mean rumba etc, I am not so interested in salsa. And of course, if anyone wants to join, let's meet up and do it :D
I've heard of Kluver Dansschool, does anyone know how it is ?
All the best,
Andra
