if you haven't got the email don't worry, if it's like last year it'll be easy to guess what it all actually is. can't remember now, so don't bother trying to ask.
for anyone considering budget en-suite, if you want to live in a broom cupboard that has an aeroplane bathroom with shower then fine, otherwise don't bother.
I got my email and applied way after now and still got in to halls, and just actually moved out today, and would say for going out to places, none of the halls other than middle mill and IQ wave are in town, all a little way out, Seething Wells is most probably easiest to get to town, with Kingston Hill being next.
If you have a disability and going for DSA you can do a form which will give you a better chance of getting in to halls, you do have to prove the disability.
For international students, I don't think they won't definitely get halls, as know some that didn't get it, but think there may be a preference. I know that there seems to be tonnes.
