t k asked: I am travelling to Santiago Chile and will have approximately 4 extra days and able to fly to another city in South America. What city would be the most interesting to visit for this short amount of time?

Mr. Senior asked: I am want to go to Colombia. Probably pick up their accent and stuff and I am wondering which city to visit. I am thinking of Barranquilla or Cali but is there any other cities that I would benefit more?
