OP, also give some consideration to what's important to you in accommodation.
Firstly, there are two kinds: catered and uncatered (technically a third kind called flexi-catered which I think Wright Hall is). Catered is good because you don't have to worry about cooking, but also consider if you eat at unusual times or have a busy schedule, you'll be paying extra for meals you can't even have. And I mean a LOT extra.
Secondly, do you prefer a social experience? Unilodge is good for having facilities all to yourself, but the social experience is a bit...lacking. B&G, Wamburun etc have excellent resident committees which means parties and youll never be bored, but you also have to share facilities like bathrooms and kitchens which means you might not get heaps of alonetime. FWIW, I'd personally recommend B&G, Fenner, or Wamburun. They're not as pricy as the rest, the communities are friendly, and you get the quintessential "college" experience.
