The grandest apartment, which belonged to Horodecki, consisted of a study, a great room and a living room, a dining room, a boudoir, a bedroom, a children's room, a room for a governess, a guest room, three rooms for servants, a kitchen, dishwashing room, bathroom, two toilets, and two storage rooms. On the floor above was an apartment similar in size and design to Horodecki's apartment. The apartment on the top floor had one less room; to make up for this, there was a connecting terrace which provided a panoramic view of the city.
