Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenants in Louis Koplowitz's buildings often note the decent locations and spacious apartments but raise consistent concerns about cleanliness, pest infestations, and common area upkeep. Management's responsiveness is frequently characterized as slow or unreliable, with multiple reports citing unaddressed maintenance and heating issues. Supers are often seen as overwhelmed or unprofessional, impacting timely repairs and overall building condition. Noise and neighbor behavior vary but can be disruptive in some places. While some tenants appreciate the rental affordability and community, many advise improvements in pest control, building cleanliness, and more proactive, professional management to enhance tenant satisfaction.

Reviews

Former tenant·9 minutes ago

Not the best

Pros

Nice location, friendly neighborhood, laundry room is great. In building gym, key fob access

Cons

We caught 8 mice in our one year living here. The hallways were always grimy and smelled like cigarette smoke. The super has several huskies that he lets out in the back alley, they poop everywhere so the back alley is usually infested with flies. The walls were so thin, we could smell the incense our neighbor would light every day, and could hear kids running around in the unit above us.

Very big apartments. Somewhat affordable

Pros

I liked the size and layout of the apartments

Cons

Constantly trying to get rid of roaches.

Advice to the owners
