The family lived in a large second-floor flat, and the garret served as a boarding house for male students.

In a letter to his friend Tytus Wojciechowski dated 27 December 1828, Frédéric mentioned that one of the former boarding-school rooms had been turned into a study for him.

It was in the Czapski (Krasiński) Palace that Frédéric Chopin composed and first played for family and friends some of his most important youthful works, including Piano Concerto No.
