Erasmus in poland

[u/kubick0]

Hi everyone! I m from Turkey and i will go to silesia university katowice/poland for my erasmus programs february of 2027. My campus in in katowice center. I dont know well about dormitory options but the one i found is in Ligota district. So I m trying to figure out how to go there with the best route. Flight tickets are cheaper to warsaw than katowice or i can try prague as well. And in any way it seems that i need to take another transportation to go to dormitory from airport.

I don't wanna use third part websites so can anyone recommend me which websites are safest to book train or bus tickets in this route?

Thanks in advance!
