Whoever put that dreadful stair carpet down should be shot.
I seem to remember garish flowery carpets from the 70's. We had some on our stairs when I was a lad.
I had forgotten how massive it is and how iconic. Is it listed, do you know?
I'm not sure. I could have told you how to get in if you wanted a bash? Just a little climbing involved!
I thought the security was a bit (up)tight when you were there, so I didn't bother crossing the road!
