Hey! I just finished my first year at Sussex staying in Northfield and can confirm, it's the best. The en-suites are a lifesaver, and it's so social despite being at the end of campus - it's like a 15 min walk tops to the other end, so you don't feel distance or anything. And you've got Northfield Bar too, which is probably the best advantage, my friends and I went there probably every other day. Block 19 is round the end I think, from memory, but even still you're next to the South Downs and it's maybe an extra 2 min walk so nothing major. You'll love it!!
