Thanks for the replies. I definitely hope I won't want to "escape" London, so Hampstead and KCH are low on my list. I like Wolfson, SSA and GDSA because they are self-catered. This may sound strange, but I just have a hard time thinking about being forced to eat food that I don't want when I'm 24 years old! Those pictures and strong recommendations for Wolfson is definitely making me consider making it my first or second choice. I also kind of like the Rectory, which I understand is for mature undergrads/grad students, has a decent location and is quite small. The more I think about it, though, the more I think I'll have Wolfson at least #2!
