Is Kensington really getting that bad? I haven't been down there in a little while, but my girlfriend still seemed to think it was going well there. She rarely goes herself, though.
That said I rent long-term (nearing a 1/2 years) in Liberty Village (Ha! I cannot afford to buy in this city) and my building seems to be half Airbnb units. I run into more people with luggage coming and going than I see actual residents. The faces are always changing except for the smallest set...
