Hi Piggy
The halls in Vale village which are closer to the main buildings at Brum are not far away at all, eg tennis courts. You could carry a cello to and fro alright (I was a cello carrier for years) but probably not a double bass. Shelly oak is a dump but strangely much loved and no worse than eg fallowfield in Manchester which I accept is a low bar.
We went to look around Glasgow at May half term when DS was thinking about Geog/environmental geoscience and I have to say it was fantastic. What a great city and I preferred it to edinburgh by a long way, which I was not expecting. Fewer tourists, less tartan tat. University really nice and in best bit of Glasgow - west end is beautiful snd fab and full of independent shops snd cafes and small cinemas and second hand book and record shops. So much going on.
