Do you have gumtree? thats a bit better. Can you search `house shares' or `spare room' see what you come up with. Ive heard Craigslist is a bit dodgy.

House sharing is hard you need to match up well. Take your time but dont dismiss your opp gender. Interests and routines are more important than gender. Unless you specifically want a girl because you dont want to feel uncomfortable around a guy.
