Falmouth university shares a campus with Exeter Penryn students, there isn’t much to do in Falmouth really but it’s a nice area. Cornwall transport is awful too you could be waiting an hour or more to get busses to and from places.
Bath Spa has frequent transport between Bristol, Bath and surrounding areas. The campus is beautiful and even though it isn’t directly in the city of bath, there is a bus every 15-20 minutes (It may be more frequent but I can’t fully remember!!) For creative subjects it’s very highly respected.
UAL i’ve heard it’s harder to get to know people as it’s less of a campus university and more spread out. Some love it and some don’t, as the hussle and bussle of the city can become overbearing.
I hope this helps a little bit as it’s purely from people I know at those unis currently. I don’t know anything about Edinburgh though!
