They may have the best buses, but they have to spend all of their money, and inevitably half of their parents' money when they go sobbing home at Christmas to get their debts paid off by daddy, on living in bleak rooms that people in the North and Wales would probably keep as a place to put boxes, bikes, camping equipment and broken TVs they can't be bothered to dump.

Twitter user Daniel Ruiz Tizon regularly trawls the estate agent sites for the very worst converted rooms and corridors, revealing such horrors as mezzanine beds not a good look if you're over 13 , converted corridors being rented out for £910 a month as if they're entire homes, and sofa beds in kitchens, all popping up as landlords convert former cupboards, attics and immersion tank spaces into homes they can charge a grand a month to put a social media intern in.
Not a nice place to live unless your dad's happy to pick up three quarters of the tab each month or you're OK with being able to control the cooker while sitting up in bed and have a fridge as a bedside table.
