I have a friend who used to rent a flat pretty much opposite Facebook's office, paid £2800/month for a 1-bed studio. Know someone else who works for a law firm in the City, he pays dead on £3000/month for a flat but he's 2 minutes away from the office and pays for that convenience. And yes, I know someone who lives in Ealing, but a 2-bed flat(not a house) is still £1900/month, and the commute was 45 minutes each way on the tube.
