Where to ride horses in Bs As (Buenos Aires)

Hi,

I'm looking for a place that rents horses for half an hour/an hour with in reach of local transportation in Bs As. Anyone has a recommendation??? My daghter who soon will be 7 years has recently moved here. In order to give her incentive to manage school without understanding the language I promised her to ride a horse. She needs that incentive desperately this weekend, please help me!!!

Thank you on beforehand!
