Why does Susanna object to the bedroom chosen for her and Figaro?

Susanna objects to the bedroom chosen for her and Figaro because of its location within the castle. While Figaro believes the room is conveniently situated near the bedrooms of the Count and Countess, Susanna warns him that it is "all too convenient" for Count Almaviva. She is aware that the Count is actively plotting with the music master, Don Basilio, to seduce her, and she fears the proximity of the room will make it easier for him to pursue his dishonorable intentions.12
