Have you already had your exam results? I'm awaiting Alevel results this week and St German's is my top choice of accommodation for Exeter (if i get the grades) - hopefully see you all there!
I was in Chagford, but I'm convinced all the St Germans blocks are the best. Small enough that you can get to know the whole block, but big enough that there's always something happening. Also, you're in a great position (close to campus, but just set off enough that you don't get all the noise).
Really spacious living and kitchen area...! Enjoy! There's also the grassy area outside by the small 'pond'. In the summer we all used to revise outside in the sun.
If it's anything like when I was there? Honestly great. I find the sort of people who go in St Germans love a party but not all all the time. So when there is a party, it's great!
