Bloomsbury is the postcode (mostly WC1) where UCL, SOAS, Birkbeck, and the Institute of Education physically sit. It's also one of the most expensive student-housing markets in London. The instinct is to live there because it's the campus. The math often disagrees.
We help you decide whether Bloomsbury's premium is worth it for you, or whether King's Cross / Holborn / Stratford / Whitechapel give you 80% of the experience for 60% of the rent. The answer depends on whether you'll be on campus 5 days a week or 2, whether you have evening commitments, and how you'll feel about the Tube at 11pm.
Below: the five neighborhoods we sort UCL students into, the honest monthly cost breakdown (in £, sourced), the visa / council-tax / bank-account practical bits no one tells you, and our hand-picked picks (limited — we're newer in London than in Chicago, fewer partners so far).
