When I lived in apartments, I always lived on the first floor, with large dogs (60+ lbs) I did not want them running on the neighbors heads. I know what that sounds like and it can lead one to drink!
Anyway, I had a dog-door for my sliding glass door. My dogs had access to the patio and to go out and do their business anytime they needed too. I cleaned it up daily, sometimes more often if they pooped more often. I did not want to draw flies or have ordor (poop or urine.) No stains, no smell...no complaints from neighbors.
They still got their walks but they were able to use the patio.
Now we are in a house with a big yard...just can't compare apples to oranges.
I vote for doing what is best for pup and mom, whatever THAT looks like.
