The English tutors are really good (quite apart from obviously knowing their stuff and being decent teachers, they're actually interested in us and very approachable). They're also keen to let us do more unusual topics/authors if there's something we're interested in, so the course can be as diverse as you want it to be. They also give you full choice over which papers to sit, which isn't the case in quite a few colleges.
Like people have said, it's not that far. I walked (very fast) from Christ Church - probably as far south as you're likely to be - to Hugh's in fifteen minutes the other day! It takes ten minutes to cycle to the English faculty, and the same to get to the centre of town. In any case, there's sufficient shops, cafes and pubs up this end of town.
I suppose it's 'quiet' in that it's not right in the centre of busy busy streets and has very peaceful lovely gardens, but it's also a large college so there's plenty of people around when you want them to be. I love the location - this part of town has lots of very nice red brick Victorian houses and trees.
Other good things: accommodation is provided onsite for the duration of your degree, which is both handy and conducive to a nice atmosphere where you know lots of people from all years. Hall food is good and cheap but everywhere has access to a kitchen as well. There's plenty of music/sport/other extra-curricular things going on, with decent facilities for these - ask if there's anything you're particularly interested in. As I said, the grounds are huge and gorgeous (we made a fruit crumble with apples from our own trees last week at Pudding Society).
Do ask if there's anything more specific you'd like to know.
