I am unfortunate enough - from a sky-watching point of view - to live in the outskirts of London, where light pollution reduces the number of visible objects in the sky by a considerable amount. I will never forget the day I ventured out in the dark in the countryside alone, and found the sheer number of stars in the sky, and their brightness, overwhelming.
My children and I have watched the skies for Geminids and Perseids and either the weather has been dull and cloudy or the light pollution has killed the experience. But I think that even we have a hope of being able to see the Comet Holmes, by the look of things. You'll find instructions here for finding the comet in the night sky, and it should be visible for at least a couple of weeks, weather and light pollution permitting.
