From my experience (Grosvenor Place, though I think all of the Grosvenor halls are essentially the same), the halls of residence themselves are just fine. The rooms have a reasonable amount of space, more than enough for all of my stuff, anyway. The kitchen has adequate food storage for everybody and 2 ovens, though in my case the kitchen permanently looked like a bomb had hit it because none of my flatmates cleaned up anything ever. Thankfully, the kitchen is cleaned twice a week because in some cases it really needs it. The other facilities are more than adequate as well and it is easy to report problems via the building maintenance system if there is anything that needs to be fixed. From what I have heard from other people, most of their experiences in halls of residence have been good too, though a friend of mine who lived in Oak House was so disgusted by the behaviour of people and state of her room that she actually moved out of halls of residence in the first month or two of university. From what I have seen, the halls of residence are good places to live and the only real factor that is likely to get in the way of your enjoyment there is other people, sometimes you get a good selection of flatmates and sometimes you just don't.
