I started out taking two weeks of group classes at Vamos and ended up staying for more because I didn't want to leave! The teachers are all knowledgable and down-to-earth people, they cater to all levels of Spanish, and the whole environment at the school is super inviting and relaxed. The daily social activities are also such a nice way to meet and hang out with new people from all over the world. Whether you're just passing through, or in Buenos Aires for a while, Vamos is a great place to learn/brush up on your Spanish!
