Try 7 and 20, but it's all down hill (it's the getting back that's the problem, lol).
The food is good, but I know they don't make the Alpen Bars (plus occasionally they buy in cakes which come in plastic trays and are all dried out) and somethimes the food can be very rich.
We have formals once a fortnight (which you have to sign up for on Trev's brilliant homepage - which has everything you will ever need to know posted on it) and are one of the few colleges to wear gowns to the university matriculation service.
Trev's is VERY friendly and the fact that even the landings are hexagonal means that you get to know people extremely quickly. Some might consider the 'mixed' landings + bathroom situation a problem though however, this hasn't really been an issue for me.
We have an excellent support system in college and it means that you always have someone to talk to if you need it. Pastoral care couldn't be better.
You may have to share a room 1 term out of 3 in your first year, there are no ensuits for first years and the kitchens can be tiny. However, most rooms have a sink, large wardrobes and inbuilt bookcases. Most of the rooms used by students are all contained within Trevs main building (Trevs is not spilt into several buildings like some of the colleges as it is quite a small college).
We have good recreational facilities (tennis/basketball court, indoor badmington court etc) and 'the barn' houses most of Trev's - very brilliant! - music groups, as well as serving as a place for quiet contemplation.
Our library is also good, although this year they are trialing a 3 week loans period on all their books (which is shorter than in most other colleges).
All in all, Trevs will steal your heart within a matter or days, I believe that for a hill college there is no other choice!!
