The university can sometimes be assumed (by people who don't know a lot about it) to not be very good simply because Bradford city has a bad reputation. The cities had some troubles in the past and its not exactly the best neighbourhood to live in, but its worth it for the university.
Bradford Uni is never going to be thought of as a big name university simply because it isn't one of the universities that does courses tonnes of people apply to. Like York university you might go to for the reputation, you'll see how fussy it is about the grades you'll assume that makes it a great university. But Bradford university is really amazing at very particular courses, and it offers courses you can't get many other places, and a lot of those other places will be terrible compared to Bradford. Like business and management, peace studies, computer animation, criminal psychology etc. If you want to do history or geography, I'd say aim higher than Bradford. If your going for something more unique, that's Bradford's speciality. It does very specific things very well. Within the circles where those things matter it has a good reputation, employers will have heard of it and not think little of it, because they know Bradford makes good students. Even if people from other uni's might not get that.
As for the town itself. I've never seen anywhere before with such a can-do attitude towards improvement, which does mean its always trying to do interesting things or have cool places being built (like a great big new London standard shopping mall which I've been told there are plans for). I'll be honest the city isn't the best place to live, its kinda dirty and there's a decent amount of crime, and there's not exactly a whole lot of money in the area. But it'll teach you to be responsible, to remember to lock doors and not to walk around alone at night. You'll feel like a more competent grown-up by the time you leave and you'll make jokes about the city with your mates. For students its kinda perfect, its rumoured to be the cheapest student living in England and I wouldn't be surprised. Drinks are cheap, nearest shops are cheap (and not the bad quality aldi cheap, morrisons and asda cheap) and rent is crazy cheap if you rent a house in the second year. Like really cheap as standard but if your luck like me you can find crazy cheap housing. (I'm going on a £2000 trip to africa with the left over money from my maintenance loan!).
The university also has just a great attitude in general, there's the fact it tries just so hard to keep pushing its degrees to be better, tonnes of opportunities like study abroad, and the fact that its waay more interested in getting its students jobs than anything else. Its not focused on academics or getting good results that make it sound better or giving you work you don't need, its first and foremost priority is to get you a job when you leave. And you can really feel that, and that's got to be your number one priority. The support for students is always massively helpful, the union will have something for everyone and even though its not a small university, it had the attitude of a small university in the way its really close knit team feeling really supportive, unlike some of these cut-throat you're on your own uni's. The long and short of it is, its a great place to study, that won't cost you a lot to study there, what more do you want?
