Cheaper accommodation/ a greater choice of accommodation (so there were some genuinely cheaper ones to chose - I really don't need a luxury ensuite...)
Nicer kitchens (bigger, cleaner - I don't think the oven had been cleaned in 50 years..., shared with less people, bigger fridge - half a shelf each really isn't enough...)
Quieter corridor - e.g. by filling in a form about your social habits before the uni allocated you to a particular corridor, so all those who wanted to party all night could do so without disturbing those of us who like some sleep
Accommodation closer to the department/ in a wider choice of locations - one of the drawbacks of the collegiate system is that most/ all of each college's accommodation is in one location, and mine just happens to be about as far away as you can get from my department...
Cheaper food in hall/ prices equalised across the university
Less work would be nice too...
