CIEE is a flipping incredible organization that sponsors a ton of international opportunities. They offer high-quality yet affordable programs. And even better--they have scholarships!!!
For example, Munich. The universities, pretzels and beer are to die for. Or something more appealing, like Augsburg. P.S. It isn't as obnoxious a city.
Amsterdam is a gorgeous metropolis with art, commerce, and learning all in one place.
Budapest and its Hungarian language provide a challenge, but one well-worth it. (Also…look at the river…)
Paris is great, but what about Aix? Nobody in their right mind would forsake a city (almost) on the sea. Schools in Brittany offer a different definition of France. Check out Rennes.
