We're not far from Oxford and my sister lives there. We went on the tour of the Christ Church College Dining Room and Cathedral, and saw something of the Bodleian Library I think, but I don't remember much of the latter.
I like the architecture and imagine it must be amazing to be immersed in it there. As an outsider though, I wouldn't want to live in Oxford. It's obviously very urban, and we sometimes get a sense that some people are a bit snooty! My sister is snooty too, so fits right in, but it grates somewhat for those of us who aren't like that. :)
