It was Kentish Town. In the mid 2000s it was really not a nice area (flats there I am sure would still have been beyond most struggling actors, but that's true of London as a whole when you have no job). They are worth more now - but still Kentish Town and Kensington bear no resemblance to one another. Kensington is the preserve of oligarchs and formerly hedge fund managers (probably now priced out).
