We once viewed a 3 bedroom flat which was one room with a bunk bed, a sofa bed and cooker and fridge in it. They wanted 800 p/m for it and two months rent as deposit. *EDIT* In regards to the bed sharing, I used to stay in a flat on Holland street which had a room with a single bed and a room with a double bed. Prior to me and my flatmae living there 4 Nigerian men lived there.
