Oxford college help urgent

Hi so I have three colleges in mind: Christ Church, Corpus Christi, and Balliol.
I want to study Law (Jurisprudence) but I am still deciding between colleges? I was really biased towards Christ Church but I have heard that people that do live there don't particularly like it? Meanwhile it is also quite hard to get accepted into Christ Church- based on statistics.
A bit about myself- I'm not a very social person unless I am put into the situation (I won't go out of my way to be extremely social but If the situation calls it then I will), I love libraries and I need a nice environment to study in, I love walking, AND ENSUITE ROOMS I CAN'T DEAL WITH SHARING BATHROOMS SADLY.

So does anyone have any advice in helping me pick maybe? or giving my recommendations please !!!!

Start by using this to identify any colleges in particular that meet all of the requirements you have in mind http://apply.oxfordsu.org/colleges/suggester/

If any of those three colleges come up, then they probably were the right choices from the start. If not, then you’ve probably got better options to look at.

Christ Church comes up as top one but I am overthinking it since it's apparently hard to get into, in addition to people not liking it??

None of the colleges are easy to get into and they can reallocate you if you happen to have applied to an oversubscribed college. If you don’t apply to christ church college, then you’ve got (almost) zero chance of getting a place there.

The question is why do these people not like it at christ church college? Is there one underlying reason that would be enough to put you off?

I'm not 100% sure, I just remember seeing it somewhere, someone said that the rep for Christ Church is that most students that live there don't particularly like being there?
