CH3ed: 
I've never been to England but I think I view 12GP the same as most here. Old New England style brownstone row house. 

I'm just wondering though, since the fidelius charm was done on the house by DD, so the effect of nobody who has not been told by DD himself (or his note) would be able to see the place just happened after the Order was recalled after GoF. Before that the muggles living nearby should have been able to see the place (but may or may not have registered it)? Since they can't see it now, if some muggles come looking for a friend's house nearby, say, and was counting down the number, wouldn't they find it strange that number 12 is missing? And what would happen if the muggle neighbors sold the building (the whole row, say) to a developer who wants to demolish it to build a mall or something? Do you think the Black's protective magic will cause them to be distracted away from doing so the way the muggles who wandered toward the QWC stadium suddenly remembered urgent errands in GoF? I don't think it would be like Hogswart where muggles just see a ruin, since Hogswart is at an isolated
 location away from the city while 12GP is right in the middle of London.
