Oh, yes it is, though, in your case, in the present context, only mildly. "It's just lovely" = "I'm getting very slightly mangled" (With a bit of luck, it also includes "And I feel all the better for it"). In a previous job, I used frequently to find myself alone, in the evening, in hotel lounges. I then found the combination of coffee with whisky in it, the "Telegraph" crossword, and the radio playing quietly the nearest thing to heaven imaginable. (Especially if I managed to complete the crossword!)
