The set that is supposed to be the room of Robert Stoner (Byron Morrow) at the marina is the one that normally is used as Peggy's apartment (e.g. as shown in Eagles Sometimes Can't Fly (1969), and Last Rites for Miss Emma (1969)).
Angel Tompkins (Barbara Stoner) and Sivi Aberg (Carla Renata) had parts in the movie The Teacher (1974).
