I’m from Colombia and as a Colombian I can recommend that you visit these cities:
-Bogotá: The capital city of Colombia is full of many different industries and businesses, beautiful and famous restaurants as well as clubs. (bohemian plana to do: I'm not too sure what you mean by this)
All around Bogotá there are many towns, famous for their food and entertainment.
The weather is between 19 and 24 degrees.
