Generally good, til you need your deposit back
Pros
We had a corner unit 1bd on the 3rd floor and a storage space - unit was spacious and bright. Few issues arose, the super helped when needed (though wasn't always the easiest to get in touch with). Elevator worked fine, no pests.
Cons
Gym / rooftop in the building across the street - were unimpressive, but adequate. Biggest hassle was trying to get my security deposit back. Unit was left in great condition, but we still had to threaten legal action to get our money back.
Advice to the owners
You have a good thing going, just treat people right
