Awesome idea, and you're right almost all new condo towers have a few Airbnb units.I believe few units are listed on Airbnb! rent a unit for couple nights to check the building out...same goes for many condos in the city. you can also see reviews from other people that rented in a building as they point out small detail.
If this is true that is atrocious, and cause for an immediate pass on this building. How could anyone live above the 7th floor with elevators like this? What is the point? You certainly wouldn't have a fast inner-city commute, as you would spend more time waiting for the elevator than in traffic.I've heard the elevators in the guardian take forever. I had some friends who lived on lower floors and they would press the elevator button, go for a shower, come out, and the elevator still wouldn't have come.
