Here's a little from Laura about Montreal:
From graffiti and abandoned buildings to empty lots and jumbled architectural styles, Montreal is unique because of its grittiness and chaos mixed with classic European style. I would characterize the city’s overall vibe as gamine, the French word for “street urchin” or “naughty child.” Additionally, the Wikipedia definition of this word points to mischievousness, or being sexually appealing, and lists Audrey Hepburn as a prime example of the style. Montreal is definitely both mischievous and sexually appealing, with its red-light district in plain view on the main drag, Ste-Catherine. However, it’s also very urchin-like, with its sooty streets, bohemian fashion sense, and the urban decay you’ll find in many major cities.
