I've just checked and yes, it's Ruth's house.

I said Ealing because it's mentioned in the audio commentaries of 4.05, minute 12 of my DVD, they say it's in Ealing and somthing more (I can't understand it well enough...) I had a look at the area with Street View and some streets are similar to Ruth's but nothing...
I've created a map in Google maps (very geeky I know ) I draw a line in the streets I've checked, but there are too many!!
