Argentina offers a land of immense contrasts with a great variety of experiences. A microcosm of the entire South American continent, holidays to Argentina are a hugely rewarding experience.
Buenos Aires stays interesting when you are surrounded by welcoming and eclectic Porteños. Cafés, cinémas, milongas. . bla blah. . are not boring in the company of Argentines themselves. Just like any city, if you have no purpose and have not formed a solid community then it won't hold your interest forever. But Baires has a lot of hidden treasures. Yo, por lo menos, moriré en Buenos Aires.
wonderful city... but i guess you're right, it's very much like Paris.
