Conservatoires

So I'm looking to apply to a conservatoire this year but, not being from Europe, I don't have any idea about the various reputations of the top Colleges.

At the moment I'm thinking about Royal Academy of Music (although when I asked them for a prospectus they were really rude so that's kinda put me off, haha), Royal College of Music, Guildhall and the Conservatoire Nationale Superieure du Musique et Danse a Paris.

Does anybody have any experience with these places? Or even know which have better or worse reputations? For example - when I first came to London I was thinking about going to Trinity, but then a couple of people have told me that the entrance level to get in is not as high and that it doesn't work to such a high standard as this others, which doesn't really appeal to me.

Thanks for any help you can give me. x
