AVOID AVOID AVOID

Pros

Nice neighborhood, balcony spaces, elevator.

Cons

Ignorant owners who refuse to address issues in a timely manner if at all. NO super present. Horrible pest issue, poor trash management, heat turned off on the coldest day of the year, refuse to fix electric issues, scheduled maintenance appointments don't show. Common areas are absolutely trashed and not maintained. Building smells of mold/mildew. Black mold in the bathroom and living area (which they offered to paint over as a fix).
