Just a few thoughts that popped into my head:
Regarding a short-term visit, I am on the fence.
- Romanian is a Romance language like Spanish, although its usefulness is mostly limited to Romania and Moldavia. English and Spanish are widely studied.
- If you are from the European Union, Romania is easier to access. It's part of the EU, a future Schengen member and geographically and culturally closer than Colombia.
- Traveling from Romania to nearby countries is also easier and cheaper.
- Romanian winter is cold, Colombian winter is warm.
- Reggaeton seems to be quite popular in Romania.
- Romania is less poor and has less crime.
- The job market isn't very good in either country but I imagine it to be easier to get a job in Romania.
- Their flags have the same colors.
