I read it decades ago, but then I watched Ex Machina and the tale came to my mind.
It was, most likely, an Asimov short tale. The lady houseowner acquired a servant male robot that would perform house jobs for her in a perfect manner, cook, clean, etc. I remember she was mesmerized with the robot's appearance: perfect hair, perfect voice, gentle, and so on. He was tireless, and always there for her.
I don't remember details, but I think she falls in love with the robot servant. And thus when I watched Ex Machina, I remembered that the ultimate Turing test of a robot is, indeed, a human being falling in love with the robot, which I believe is the point in the movie.
Does anyone remember which story this is, and from which book?
