Buenos Aires - Europe in South America
Buenos Aires is a very interesting city: in my mind, it is a mixture of New York, Paris and Lima. It is a stark contrast to the typical Latin America city. If you are from Europe you may be less impressed with it. The food there is great; YOU SHOULD EAT STEAK FOR EVERY MEAL UNTIL YOU GET SICK OF IT. Empandas are also good and cheap. Transportation is mainly done by bus and is easy and affordable.
Insider Tip:You must use the black market to exchange your money, you will effectively double your money by doing so. Bring US Dollars into Argentina and head down to Florida St first thing from the airport (there is a lot of accommodation nearby if you really want to plan; San Telmo is a good area to stay in). People will be shouting "Cambio", go up to them and ask them for their rates and find one you are happy with. All of this is perfectly safe and a way of life there. Police patrol the street protecting everyone.
