I like the townie suggestion. Theft was a major problem at my school in the US and I know many Townies do not have any quick releases. This is something I would highly recommend, make sure whatever bike you get does not have quick releases, it will make things easier. Also, the townie will have fenders and racks to help carry stuff. This is assuming she wants something just for cruising to places, class, etc. If she wants to get in some serious riding, I would look for something different.
