Damn. I live in Poland and pay around 500USD for a comfy apartment in one of the best neighbourhoods in the city, close to nice parks and to every store you need. I definitely recommend making the move if you are willing to learn Polish (not needed at all for a job in IT, but useful if you want to live here long term). Worst case scenario you can always move back. That's what I was thinking when I moved, but in the end I decided to stay.
