Last year I stayed in Oak House in Fallowfield, and the Fallowfield campus is generally agreed as the most sociable, though it is also the furthest from the University by quite a margin.
I have heard stories from people living in Grovesnor last year that the halls(and City campus in general) weren't very sociable and contained a lot of internationals and British people who didn't really want to socialise, but it does happen in all halls.
Regardless, I would recommend Oak House(or Owens Park, if you want catered) but some argue it's too threadbare and basic, but it's up to you.
I picked Intensive Latin(both semesters) and The Odyssey. The Odyssey was alright but not perfect. I enjoyed the text itself, and the course was better than other things I've done at University.
Latin was fun, and I would recommend picking a language to do in First Year, as it doesn't count towards your classification if you fail it and you can see if you want to continue with it. For instance, I enjoyed it and am currently doing Advanced Latin after passing Intensive last year. Intensive Latin cost 20 credits per semester, so that's why I only picked 1 other elective, iirc.
This year, I picked Cicero, which I did not enjoy whatsoever, and Graeco-Roman Egypt, which I am enjoying.
I preferred the Roman Republic to Archaic Greece, but both lecturers were good, I just preferred the actuality of Rome to the relative unknown of Greece.
If you have any other questions, don't hesitate to ask.
