We're hoping to explorer Bacelona and South of France from Switzerland on long weekends.

Not sure where live in Zurich yet. Given our wish list -
(Culturally diverse, outdoor lifestyle, street cafe culture, healthy eating, public transport (hate cars), cinemas, waterside, weather,
cleanliness, personal safety...)

We are thinking (from reading these pages) Seefeld or even NiederdorfS.
We are recently married 30 somethings.

Is there good gym/healthclub and tennis courts nearby these areas?
This are essential...
