For sisters planning to study in London, where else can we live??

Sisters who are looking for affordable housing, don't worry, there are currently limited options available! Well, I can't say it's completely unavailable, but the availability is extremely limited... When is the best time to start looking for suitable housing? Start looking at the end of June or early July, as that's when social housing for September becomes available. For those who are starting to search for housing now, I'd like to ask if there are any UCL, KCL, ICL, LSE, or LCC students here. Do you need a collection of apartment options?
