Yeah, I moved to poland for four months for basically this reasons.

It seemed kind of bizarre, but it did make my money last a lot longer, even with the travel cost of getting there and back.

However, I had a friend to move in with so I wouldn't get lonely in an environment where I didn't know the language or culture. Without this, it probably would have been impossible. (I would likely have gotten depressed and unable to get any work done.)
