For the price, it's worth the troubles.
Pros
The rent, the location, the units facing the park, superintendent is responsive and quick to fix things. Neighbors can appear stand-off-ish but are mostly friendly once you start chatting.
Cons
Can be a bit noisy and dirty. During the winter its common for someone to be smoking in the stairwell, whether they live in the building or not. And there's a group of guys at the retail shop next door that are consistently cat-calling any young woman who walks by.
Advice to the owners
Give the superintendent Ivan a raise!
Look elsewhere
