I mean, we can talk about price jumps between bedroom counts if you want but I'm not sure it's very relevant to the article, which is saying there's only "stabbyville" and "safe" places given other fixed requirements. If you need a studio in London, they exist all through the price spectrum, area spectrum, and other dimensions. I suspect the 'jump' you see from one bed to two is that, on average, two beds are in nicer areas, or they are houses rather than flats, freehold rather than lease, etc. Bedroom count is correlated with other features that also increase the average price. But that doesn't mean there aren't two beds in cheaper areas too.

The typical tradeoff in London is price vs proximity to work/transport. For most people. Safety comes in at the very bottom end, but still you can live far out and commute. I'm not saying that's a pleasant experience, or that being poor is a pleasant experience in general, but the tradeoff and choice exists. If you have a job in central London that you'd commute to though, fact is you are already probably well off compared to most of the country. It's a bit like how student debt mostly affects the middle class. Same with expensive season tickets for the train.
