Through the years, the building provided accommodation from to a number of prominent guests, such as Tadeusz Różewicz, Norman Davies, Kazimierz Kutz, Ryszard Kapuściński, Franciszek Starowieyski, Rita Gombrowicz, Laco Adamik, Tomasz Strzembosz, Krzysztof Pieczyński, or Michał Żebrowski. For many years, the house was inhabited by Professor Stanisław Pigoń – an eminent literary historian and educator, prisoner of Sachsenchausen concentration camp – whose name it now bears. It was also visited by Karol Wojtyła, the later pope John Paul II, who came here both as a JU student and professor’s associate. According to an anecdote told on the 100th anniversary of the building construction by the then-head of the Guesthouse Ms. Halina Sulma, when visiting his fellow students, with whom he often engaged in long discussions, Karol Wojtyła was sometimes forced to stay overnight. During one of such stays, someone allegedly stuck to the room door a following note: ‘Karol Wojtyła – a beginner saint’.
