    Review Summary for 4109 9 Ave
    Summarized from anonymous rental reviews on openigloo.
    Recent reviews for 4109 9 Ave, Brooklyn highlight large apartments with good natural light and a convenient location near transit. Residents appreciate a friendly super and porter. However, persistent issues with pests—including bedbugs, roaches, and mice—are a major concern, with many tenants noting inadequate and slow management responses. Maintenance problems like leaks, mold, and ceiling damage are common, often exacerbated by unresponsive or dismissive staff. Heating and water pressure quality vary, and noise levels fluctuate. Rent stabilization status is unclear. Overall, while affordable, the building struggles with fundamental upkeep and pest control, impacting tenant satisfaction and trust in management.

    Pests and overall bare bones maintenance.
    Former Tenant
    Pros:
    Large apartments. Friendly super and porter. Nice area and affordable rent.
    Cons:
    Repeated bedbug episodes. Building management would treat, but just the bare minimum treatment. It became musical chairs of rotating apartments with bedbugs, since some tenants were not taking care of their apartments or would hide that they had a bedbug problem and lax treatment from management perpetuated the issue. This was several years back; hopefully, the situation has improved.
    Advice to owner:
    If you have bedbugs in a property, you must go after the issue in full force and educate your tenants to speak up when they have a problem. One apartments bedbug problem becomes the problem of all their neighbors. An infestation can really destroy the mental health and well being of someone living through it.

    Not a Good Place to Live
    Former Tenant
    Pros:
    The size of the apartment, amount of natural light, location to train
    Cons:
    They shut off the hot water all the time, there are roaches, they take a while to actually fix things, the neighbors overflow tubs causing leaks that transpire to entire ceilings coming down, mold, landlord acts like they are unaware of issues and more.
    Advice to owner:
