Could be worse
Pros
Great location (close to subway, waterfront, great food and shopping), pretty decent apartment, most of the neighbors were awesome, Elegante is a few short blocks away with the square in Brooklyn, rooftop garden.
Cons
Mice, drummer practicing in one of the apartments, athletic sex man lived on top floor, unsealed crumbling bricks on apartment walls.
Advice to the owners
Sell the place to someone with more interested in being a landlord.
