2. Venice, Italy
It’s stinking as it’s sinking. Though Venice is undeniably beautiful, the canals are still used largely to route the city’s sewage. That, combined with the diesel of all those motorboats, can lead to a pretty foul smell. Especially during the summer when everything is hot, humid, and um, fragrant.
Make the best of it: Hey, you’re in Venice. Hold your breath for a few minutes, sip that Bellini, and just take it all in.
