I totally agree with others that noise is a relative term and what I consider noisy you may not, etc. I'm answering this as a past resident to give you my experiences :) I lived in the North End, on the water side of Hanover Street years ago. Yes, I did think it could be noisy but the energy of living amist all of the activity and an amazing community made it worthwhile for me! I loved living right one one of the major streets and having everything right outside my door. My biggest issue was actually the garbage trucks coming around overnight... sometimes 2-4AM in the morning. My apartment was on the 3rd floor and my room was right on the street. In the summer, it would startle me awake! I think if you pay attention to the placement of your apartment and your bedroom, you won't notice the "noise" so much. In your apartment hunting, make sure you find an agent that has experience renting in that area of town. Apartments move quick there!
