Chile's capital city is Santiago with 5 million people, a modern, clean, cheap and efficient Metro, opera, modern hotels and restaurants. It is quite cosmopolitan with shopping malls that would rival any in the world and trendy areas with great dining and trendy shops. You can count on the Chilean hospitality that almost more than makes up for language problems you may have. Santiago is the business center with the government offices, stock exchange and for transportation features a large and modern International Airport at Pudahuel, about 15 miles from Santiago. Santiago has some great tourist things like San Cristobal hill that has spectacular city views. It is an easy city to get around in and has more buses per capita than anywhere, and they are all yellow. Cabs are cheap but they are not yellow, well the tops usually are, and the metro (subway) is clean and very efficient and only charges about 45 cents to go wherever you want.
