I already spent 6 weeks in Krakow at the Jagiellonian University's program but my impression of that program was not good - the teachers were ok but the dorm living situation was intolerable.
I didn't pay attention, I'm quite symbiotic in a sense, but I think the uni dorm would be just the same in Lublin for you - shared rooms, full of noisy youngsters. Just as
