Hey, well it kind of depends which flat you in and where you room is. I was on the back of Stenton so the noise didn't really affect me, whereas my flatmates who lived on the front side, said it was a bit of a pain. But I believe they have finished all the noisy digging out of foundations etc now and just building the places so hopefully it will not be noisy.
Also, the noise was daytime hours so normally most people are out at lectures and stuff anyway. I chose to live in either Stenton or Mackinder and was put in Mackinder this year, so I really didn't mind. You will love Stenton!
