Hi Katy,
Nice to meet you!
Funnily enough, that's quite a similar range of choices that I had made back in my day of applying to uni

- I eventually decided on Plymouth because of the city and location really. Very few places in the UK where you can go straight from a lecture, grab a bite to eat in the city centre and then be sitting by the sea all within 20 minutes! In fact that's what I did yesterday, minus the lecture of course!

In terms of commuting, would you be staying at home or just looking to live a little further out? There's so many accommodation options you'd be able to find private accommodation pretty much anywhere in the city (or further afield!), and all of the Uni managed- or approved-Halls are pretty central to the city and main campus.
Whilst Halls can be great to meet people straight away (as you're all thrust together from day 1!) it's definitely not the only way to make friends. In fact a lot of my friends (who I'm still talking to or meeting nearly a decade later!) didn't stay in Halls themselves, whereas I did. That's the good thing about uni really, because there's so many different ways to meet people - accommodation, societies, your course, nights out, etc - if you put yourself out there it wont be long 'til you find your "tribe", as they say

.
Here's some info about our Uni-managed Halls -
