I am final year student at University of Warsaw, Poland.
Jacek was a great guest. He got in early, was respectful and picked up after himself. We'd definitely host him again.
Having jacek as our guest was a good experience one that i would recommend to anyone
Jacek stayed in my apartment while I was away for the weekend. When I returned, the place was exactly as I had left it. He was very clean, courteous, and respectful of the space.
