There is nothing "so bad" about it, it's merely the fact that when you're a first year it's all about meeting loads of your peers, having a good time, experiencing living with people on your corridor etc etc. Our concerns about Rosie going to Neuadd Willis, were based on the fact that mostly non freshers will be living there and it's nice to have friends close by who are in the same situation; new to uni etc.
It looks really nice from what I've seen, I was just expressing my view that I think first year students, in my opinion, should be surrounded by other first years.
Of course it depends on the person, and if someone doesn't mind being in different accommodation to almost every other fresher and can make friends easily without needing a corridor full of nervous students then great.
