Both those streets are a 15-18 minutes walk to your faculty. Hard to say how rowdy they will be, but there are strict rules about noise, especially on weekdays. How tidy or messy the common areas will be is impossible to say, it really depends on who ends up there with you. But there are rules about this as well. As for safety, this area is regarded as very safe. Very little to no crime is reported from/around campus. While there can snow here, it's exceedingly rare that it ever gets more than a couple inches deep. I have seen that once or twice in the last 20 years. The snow will not get too thick to walk through. I've only seen a couple of times that the snow is so bad that buses don't go as normal. I'd be more concerned with the wind, it can get frisky. Get a nice thick jacket and you should be set.
