It'll be fine! I stayed in Radisson SAS Scandinavia in Oslo last weekend and it was a great hotel, if you have any doubts you can check out tripadvisor.com.
I've never actually stayed there, but I'm often in Leeds. From the outside it looks good, and the location's ideal - right in the centre of the city. Some of the rooms appear to overlook the various bars and restaurants in The Light centre, so if you're planning on going to bed before 11pm you might want to ask for a room on another side of the building.
