Have to say York. I'm a bit of a football purist, some might see Bootham Crescent as a dump, I love it. Nothing much has changed since my first visit in the late 80's to my last visit in 2012, where I actually went in the home end. It has character and charm in abundance. It's also where I received my first kicking at a match in the mid 90's but that's another story.
The city itself is one of my favourite places too.
