This sentence is still confusing me

[sondra]

Dear teachers,
I asked if I could say :"He saw a pretty woman standing by the fireplace through the window."
But it was not correct as it sounded as if the fireplace was through the window and that I was not saying anything about the location of him. But does the correct sentence show his location?
The fireplace is really through the window in the room, and the woman is standing next to it. I do not know where the man is standing. But I think he was outside when he noticed her standing by the fireplace, in her room. Or maybe he was in his own house and as their houses were facing each other
he saw her.Should I show the man`s location? What do you think, where he was standing?
What if I say :"By the fireplace through the window he saw a pretty woman."
Would it be correct. Whom 'Through the window' refer to?
I did not understand my mistake.

Thank you.

He is outside the house.
The woman is by the fireplace.

But the sentence should be clearer if we rephrased as I'll write below;

The woman by the fireplace version;
He saw a pretty woman who was standing by the fireplace, through the window.

The man by the fireplace version;
He saw a pretty woman through the window, while he was standing by the fireplace.
