William is a narrow, old street - bordering on a lane - that comes off Oxford Street. It is lined on both sides with rows of terraces. Most, if not all, these terraces are retail or commercial, rather than residential. It is a lane of boutiques designing and selling world class jewellery and fashion, sporting names like Collette Dinnigan and Leona Edmiston.
Let's start with the more prosaic. Here, we have a cobbler's shop and a dry cleaner's shop. Both very fine establishments, I am sure.
