Impossible to say outright, you rent will largely be dictated by where abouts in the county you are going to be living as some places are more expensive than others. But like someone above has said you should be aiming to pay as little for rent as is reasonably possible. Don't bother wasting money on expensive luxury accommodation or en suite if you don't need it or don't really want it, or can avoid it. As someone above said having a slightly larger room or being able to piss in your own toilet isn't likely to make your happiness at university much different, but not being able to afford to go out with your friends and worrying about money most certainly will affect your happiness.
You could be putting yourself at a financial disadvantage for the rest of the year, so choose wisely. And don't sign a tenancy agreement for anything until you are 100% sure you want to live there and have written up a yearly budget to make sure you can afford it. Remember tenancy agreements are legally binding documents, a lot of students don't realise this when they try to back out of the accommodation or just uni in general and realise they still have to pay rent.
