En-suite is more expensive and in my opinion not worth it unless you have a morbid horror of sharing a bathroom. The non-ensuite bit of the room will necessarily be smaller to fiot the bathroom in, although sometimes it's not strictly ensuite, just a private lockable bathroom across the corridor.
The top floor of Cripps has much bigger and nicer rooms, but it's also *much* more expensive. Otherwise I'd recommend going for first or second floor - stairs are hard work, especially when moving in with all your stuff!
Inward-views tend to be cheaper, but they have the disadvantage of a) a view into the ugly Cripps' Court b) people can see into your window from the rooms across the court. (I have a friend who got caught out by the fact that when it is dark outside and your room light is on, the net curtain doesn't help all that much!
) Outward-views are (often) prettier, if pricier. Oh, and with some of them you have the snag of random people outside being able to look into your window, it's just less likely to happen than with a court view. C staircase has a nice view of the grove, which is pretty, and B faces the river, which is also pretty, but gets noisy in summer because of the tourists and people on punts.
Hope this helps.
I'm almost certainly going to get stuck in a tiny room in bloody Cripps again, given that degrading means I don't get a choice of accomodation. Do not want. -_- As long as it isn't above the second floor though...
