I have been living in Medellin over a year and do not care for it. I like Colombians, but Paisas are quite the different breed. Have lived in Cartagena and Bogota and visited Barranquilla and Bucaramanga. I'll probably be moving to Buca. It appears to be the most livable of Colombian cities, albeit virtually without other expats. Which can be tough.
I joined expat.com on 23 March 2013.
