What evidence is there that Mr.Hyde's rooms are furnished by Dr.Jekyll?

Actually the rooms are furnished quite differently. Dr. Jekyll's room is “furnished with luxury and good taste” while the Hyde’s room “bore every mark of having been recently and hurriedly ransacked”. The rooms reflect both men's respective "personalities". Jekyll is a man of high society. He cares about money and appearances while Jekyll is merely concerned with indulging in his evil compulsions.
