yeah sorry I meant International hall...about canterbury all I know is that it has a wonderful park-like square in front.. adjacent to tavistock square - hence quite close other intercollegiate halls (connaught, international, college, commonwealth etc.). My girlfriend's brother, who is hoping to come to ucl, obviously did some research about his accommodation for next year and concluded that canterbury was the best choice. The rooms appear to be a bit more human-sized than in International - and they have all been recently refurbished. Oh, and unlike international hall where there are no en-suite rooms, canterbury does have a few with their own bathrooms and the rest share a bathroom between two - so even if you don't manage to secure an en-suite room it should be ok.
Oh, you should also consider nutford house - the location is great and the rooms are quite big - definitely bigger than International and plausibly bigger than canterbury/hughes - though not as new.
Ah yeah and in most halls whether collegiate or intercollegiate - you can get broadband internet for the whole year for 60 quid - true bargain - though keep in mind that in intercollegiate halls they tend to be quite fussy about p2p etc...in ucl halls this problem does not arise - I have been downloading a myriad of files since September and no one has told me off yet.
