Yep, they are clean when you get there, but belive me, - it won't last. Me and my flatmates are 'relatively' clean and tidy people, though you wouldn't belive it judging by the state of our flat. I've managed to build up a tolerance to it now though, and can ignore the dirt, mess, grime and left-over food scattered everywhere! - Whereas previously I'd been known to do a 'Monica' and have cleaning up sprees!
