really..... there are families with multiple children (who work hard) who can't afford to do that outside of London. You're a student studying in London (bad choice of location in my opinion being the capital and all that
), you're not supposed to be living in a life of luxury.
4 bedrooms for 2 people, who will likely be in the same bed anyway is overkill, I can understand 2 bedrooms but 4.... and I live in the countryside and always had 2 rooms (bedroom and a room that was kind of my own space and or office) while growing up
At uni I shared with other people and had one room, it's part of uni life. Lower your standards/expectations and you might find somewhere although £1000 a month isn't a lot in London
