The main airports in Warsaw, Katowice and Krakow are within easy reach. First, you need to get from the airport to the main train station. At the aforementioned airports, there is good communication between the airport and the train station.
Once you get to the main station, catch a train to Czestochowa.

You can also use other means of transportation, such as the bus.
While in Czestochowa, you can catch a tram (You can find the tram schedule here - https://www.mmpk.info/) or a taxi. The taxi stand is located next to the train station. All you need to do is give the driver the address of your dormitory. You should not pay more than 30 zloty for a ride from the train station to your dorm.
You can use the taxi on the app.
One more thing - if you decide to travel by tram, don't forget to put your ticket in the machine (then there is information that you have punched the ticket and it is valid)
