Gym class (Zumba) buddy (Vienna)

Hy! I am thinking on joining a gym, but I would need a partner to motivate me. I would like to attend a gym which has also classes like zumba..it looks on the internet like an interesting method to combine workout with dance..I do not have a specific gym in mind as I also do not know a good one, so advice is welcome, but within a reasonable price range. Anybody interested?
