i was fr Templeton. fantastic facility, the best among all the oxford colleges. a lit bit far fr city centre (2 miles), but manageable, 15 min by bike to business school, and the college has a shuffle bus running every morning and evening. i would say the only down side is you don't have the reputation of those old established colleges like Christ Church or St Johns.
it has 17 rooms for singles, and 3 for couples. not a lot, indeed. but if you successfully get it, you will definitely enjoy the service and facilities.
