It must be freezing because the windows are terrible and she has no central heating, I speak from experience. My house had double glazing but gaps in the windows were wooden frames was rotting. The cold chill came through them, then the boiler broke, we had no heating and it was freezing. Fortunately my house isn’t hugely exposed and there are trees around it that break the wind. We replaced the windows and boiler, and now I don’t wear a woollen hat inside anymore!
She is in an exposed house that doesn’t have central heating with single glazed ancient windows and stone floors. There is no way it isn’t cold.
