Hey, I'm at Sussex now, I lived in Lewes Court non en-suite initially but now I've moved to East Slope, I would suggest Park houses/ park villages, because they are middle of the range; quite a lot of people and close enough to the learning facilities. They are social within limits whereas east slope is a big party all the time. Bar in mind though that the kitchen can be quite small in those palaces.
I would say at first having an en-suite seems attractive but I don't think its always work it, its unlikely you're all going to want to shower at the same time.
Generally, those price of accommodation is quite high, which can be frustrating.
