hey,
im from that way (lived in horley most my life)
I'd pretty much agree with what others have said, maidenbower, just behind three bridges station is lovely, and three bridges actually has more direct trains to london than crawley. u should be able to get a reasonable sized place fot your money too. quite a lot of crawley is, how shall i say....full of...eerrrm...well chavs!! its ok, and some areas are nice, but you really need to look carefully, it used to be just certain areas but now u kinda have to stork the road you wanna live and be on 'chav watch!!!'
i'd defo say that three bridges and maidenbower are your best bets tho. there are quite a few houses that are nice that you could walk to the station from, but like someone else said they are all modern houses, so not much charector, and pretty much non existant gardens!!
HTH
