Mapquest

You don't need a roadmap to find your way around this easy-to-use site. Via the Locator, simply enter in the house number, street, city and postcode you're looking for. A map pops up reasonably quickly, which you're then free to fiddle around with in whatever way suits your fancy. Zoom in, zoom out, change the style, move from north to south to west to east, change the style, change the colouring to greyscale so you can print it out… You can then download it, fax it or, should you want to give people directions email it off to them. You can suss out the driving directions too, either in the UK, Europe or North America. It's all mapped out for you here.
