They do have a lot of concerts in the park over the summer and they are pretty annoying.
But yeah, that area of town is absolutely fine. I'm not sure I would fancy living that close to town just because of parking and noise.
There are two train stations as well- one in the centre of town and one further out. The further out one is the main line from Norwich to London and is a fair walk from town- about 15-20 minutes. Doesn't bother me as I don't mind a walk but worth thinking about if you are going to be commuting fairly regularly.
