Former tenant·4 minutes ago

Zero Insulation. Expect an expensive Gas Bill.

Pros

Love our neighbors.

Cons

The vents don’t work properly in our bedrooms and the house isn’t insulated. Average bill runs $500+ in the winter. Vents don’t work properly in bathrooms either. You ask them to fix something and they say they will, but don’t. Eventually you just stop asking. The “courtyard” hasn’t been cleaned once since we moved in and floods often. You can’t go out there. Mold keeps coming back on the walls and ceiling where they tried to paint over.

It Did the Job

Pros

Everyone who lived in the building was lovely, I could not have asked for better neighbors. Extremely pet friendly.

Cons

The management never responded to any problems (unless FINED by 311) and blamed tenants for everything- even cracks in the ceilings. The stairwell is hardly ever cleaned. The stoop is never cleaned in the winter, ever (at least no rats then). The neighborhood loves harassing women.

Advice to the owners

Come to the property sometime???
