I think the Uni would (definitely SHOULD, at least) be open to swapping her if she's not loving the arrangements after a couple of weeks.
With the number of hours my engineering course was, I'd have found it utterly claustrophobic to be living with them too, male or female (except there weren't enough females to even fill a flat, which may still be the case for her year, different topic, sigh!)
My large corridor of all females with shared showers, loos & kitchens was just as much of a pigsty as any of the blokes areas I knew though tbh. And after a few weeks, you were bumping into other people's boyfriends in the shared areas anyway.
But agree:
A. she might find it harder to meet other girls if she's not got flatmates as a starter to meet those doing other courses and
B. it might be a but full on both working and living with the same people when you've not picked them (moving to a house in 2nd year with chosen coursemates is a different thing).
Good luck anyway, may work out swimmingly, but she always has the fallback of asking for a bit more of a cross-section of university life, without a change of location having to be a full on falling out!
