Haven't been there, but I have friends there who enjoy it. The social aspect can be a bit bad in that a lot of people keep to themselves, so make sure that you try to meet people there and get out of your room a bit. But my friends there seem to play a lot of Xbox 360 together and party it up a fair bit, so it should be fine.
I think the rooms are pretty small, but I haven't seen any, so I wouldn't really know... And you have to cook for yourself, which would be a bit weird.
Fenner had awesome sports teams last year though, which was very unusual. Because so many decent people are getting rejected from Johns and Burgie and Bruce, the rejects that Fenner has picked up the last few years have been pretty normal, social, sporty people, which makes a change from what it used to be like.
