Despite lack of English (and our lack of Spanish), we managed to get some pesos and sort out a taxi, for the 45 minute drive to Palermo, an area of Buenos Aires where we have rented a 2 bedroom apartment for a month, with pool and gym.
We didn't achieve too much the first couple of days, still tired from our journey, and the last 5 days in Miami.
Argentina is the second largest country in South America and the eighth-largest country in the world by land area, and the largest among Spanish-speaking nations, though Mexico, Colombia and Spain are more populous. Argentina's continental area is between the Andes mountain range in the west and the Atlantic Ocean in the east. It borders Paraguay and Bolivia to the north, Brazil and Uruguay to the northeast, and Chile to the west and south.
It has a population of 40 million, about 19 million in Buenos Aires. It covers just over 1 million square miles, being 2,400 miles long from north to south and about 870 miles max from east to west.
Argentina is one of South America's largest economies with a high quality of life.
