I'm currently in London and as far as sight-seeing goes for a Doctor Who fan ... well, let's just say a picture of Bad Wolf's flat would be the whovianst thing to send back to my fellow Whovians back at home.
Is the address known? Can somebody extrapolate this? I think there was an episode where you could see some well known buildings out of the apartment's window, but I don't remember which.
I mean we see a lot of spots around her place, there should be something recognisable, right?
Edit: Clarification, just to make sure. I'm NOT talking about the place where Billie Piper lives, but the address of the Rose Tyler's home.
