My Ukrainian fiancee has taken a liking to Slupsk. She is a medical student with about 1 year left. I am curious about the cost differential between Slupsk and Warsaw. Personally I have around 6,000 PLN a month available should we attempt to move there. Any thoughts or comments would be appreciated. FYI, I am American.
