It's a really good campus, out of the universities I've been to (Leicester, DeMontfort, Loughborough, Manchester Metropolitan, Staffordshire) Hull has the best campus. Except University of Birmingham. That has the best campus in England.
When I went for an open day they were still constructing their new library, apparently it's going to be the best university library in England, but don't quote me on that.
I've heard the Uni wifi (across campus, halls, and student houses) is nothing but amazing, but apparently you have to split the speed between devices (10Mbps free, can upgrade to 25 or 100Mbps at a cost). Now don't quote me on this either but all student houses are given a free router to access the Uni wifi on, so if you buy a house in Hull you and your family could get free 10Mbps wifi and router.
Student Union building is awesome, they also won best student union of the year a number of times (Leicester won it this year (which surprised me because I saw nothing about their Student Union at their open day))
