Streetcars turning onto King from Charlotte generate a lot of noise. With windows closed, it becomes nothing more than urban ambiance. The noise will be probably be reduced with the new streetcar designs, but there are also loads of drunk clubbers between 12-3am and probably the worst downtown traffic on Thursday and Saturday nights. And constant construction in the near future: across the street (King-Charlotte by Brad J. Lamb), a condo on the LCBO site, and another condo on the commercial building next to that. And now the Shoppers building too, apparently.
Tons of great indie coffee shops to keep you going after sleepless nights, though!
