I studied at Elebaires for a couple of weeks, and I had a great experience! The classes are fun, interactive, educational and a lot of oral practice. Also the after school activities are always fun and you learn a lot about history, culture and all what Argentina (and in particular Buenos Aires) has to offer. The staff is friendly, helpful and always there so you can enjoy your stay! The pick-up from the airport was great and well-organized. It made it easier to go straigt away to the accommodation.
Lastly, there is a 24/7 helpdesk available, for any emergencies. This makes the stay even more recommendable, since they will never let you down.
¡Vale la pena!
