The Courts design can vary a lot depending when they were built but are generally okay. The higher number ones have larger kitchens/living areas and top floor ones often have balconies which is a bonus.
They are usually well looked after and the maintenance guys will quickly fix any problems but it's up to you and your roommates to keep it nice and clean (They are designed to be pretty easy to clean anyhow).
Where are you from? Often the Chinese international students are housed in the slight older Courts 3 and 4.
