The 24 to a kitchen is only in County, so far as I am aware. (Waits for someone to come along and tell me I am wrong...)
The problem with choosing college accommodation is that most colleges have a variety available and it is not all in the same place - like Grizedale includes the tower, Pendle have some houses on South West, and goodness knows who has George Fox next year. So choosing a college does not necessarily mean choosing the type or location of accommodation. You need to be aware of both factors when you are considering your choice.
Having said all of which, it is fairly random whether you get your choice of college anyway, so the essential thing is to be flexible, be prepared to go anywhere, and believe us when you say that you will be fine wherever you end up and you will love your college. whichever it is.
