Cartagena is a beautiful, small city that's mostly for tourism. I go there approx. once per year. Medellin is a mid-sized city with a perfect climate. It's currently the safest major city in the country. It's the most modern city as well. It has acquired a great reputation as a place to live and a lot of people are coming here. For example, I'm currently staying in my grandma's apartment and the guys of the apartment below are american, the ones above are german and the ones in front are portuguese. Bogotá is the capital city; you'll find the best universities, best companies, etc. here. It's a big city with a nice cold climate. Lots of startups there BTW, including Authy (YC S12), Platzi (YC W15) and Rappi (YC W16).
