My niece (late 20s) is coming to London from abroad for one year. Her employer is giving her £2.5k a month for rent. Her work will be based in Stratford. I’m reliving my youth vicariously through her but where would you rent if you only had a year and your boss was giving you this towards rent? She would be happy to top it up a bit but I would hope she is sensible and doesn’t go too crazy.
