Good Evening Debra,
Thank you for taking the time to provide some feedback. I decided on a Basenji for a few reasons. I like that they are athletic and active since I am also very active when the chicago weather permits. Their intelligence, low maintenance when it comes to grooming, etc. The only negative negative characteristic was aggression towards other dogs since there are so many in my building.
As most people do these days, I'm getting all of my information off line from what I'm hoping are subject matter experts writing these articles (obviously that's not always the case). That being said, there are quite a few pages that disagree with you about a basenji not being a good breed for apartment living. They include:

I'm sure we could argue the validity of these sources, but I'd love to hear why you think they might not thrive in an urban apartment situation. I posted because I'm trying to educate myself before finalizing this decision. I'm thankful for all opinions!
