Activities for spanish spoken seniors (Geneva)

Hello everyone,
I' m looking for my columbian mother in law some activities while she is in Geneva.
My wife is in the hospital (malaria), and My spanish is very bad and I don't have a lot of time to take care of my very nice mother-in-law who is 70.
She only speak spanish and it would be nice for her to meet people of her age too.

Do you have any ideas?

I thank you very much in advance.

Warm regards,

Fred
