Iwaszkiewicz named Stawisko. It currently houses a museum devoted to Iwaszkiewicz and his wife. They had two daughters: Maria (1924–2019) and Teresa (1928–2012). Iwaszkiewicz was bisexual and homoerotic; those themes are present in his poetry and prose works. In his diaries he describes himself as a "homosexual"; however, in light of the current understanding of human sexual orientation and his biography, he can be characterized as a bisexual. Iwaszkiewicz experienced and described a particularly intense relationship with a younger man terminally ill with tuberculosis; it commenced when the writer was over sixty years old. His wife always "knew of all of his affections". In 2012, his great-granddaughter Ludwika Włodek wrote a best-selling biographical book about the life of her great-grandfather, titled Pra.
