Another one of my many pre UKP punts from years ago. In fact come to think of it I've seen three girls from this flat. First was horrific, cant even remember her name, second was a redheaded girl, very sweet (saw her on her first day at that flat) and last was Emma who I also saw pretty early on in her first week must be early last year or even 2013.
Can see that its now £20 more as the OP said which is pushing it I think.
Not that I really give a damn about what people think, I never did like climbing those stairs as you were so exposed and everyone around on that estate knew what you were doing there !
