Birmingham: A large Campus, within a City. Some lovely facilities. A lot more greenery than people who haven't been to Birmingham expect. (On campus, but also throughout large swathes of the City). Birmingham has trees everywhere and nearly 600 parks and green spaces managed by the parks departments. There is a train line into the City Centre (two stops) and the station is in the middle of the University. Med school on the same site. The area students live in 2nd and 3rd year is a real student area with bars, food places, and practical stuff like supermarkets. Buses every 4 mins or so into the City Centre too. The City Cetnre is also a lot nicer than most people who have never been, expect.
Leeds : I haven't been but my dd really liked it.
York : 1960s purpose built campus, just on the outskirts of the City. City is obviously beautiful and full of tourists but still have enough affordable shops, pubs etc for folk that live there. Being a small, historic, walled City, although the Uni is on the outskirts, you can walk into the Centre. Much of the Accommodation is on campus but they now also have another student village with more accommodation. When we looked round they made quite a thing of it being collegiate - don't know how that impacts particularly as the course didn't suit dd when she looked closer.
Newcastle - never been
Nottingham : I really liked. Another quite spacious, quite green campus within a City. A tram takes you into the City centre - about 20mins trip. City centre looked nice - lots of shopping and night life, plus major sports grounds etc, like Birmingham (good for jobs). The med school (where a variety of courses happen, not just medicine) isn't so green - seems to be split over a major road. I came away with a really nice 'feel' for Nottingham, but my dd said 'there was nothing wrong with it, but I just didn't get that 'feel' ??
Don't know if that helps. dd is at the end of Yr 13 so we did our tours only last Autumn.
