Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback for buildings managed by Magdalena Kosz reveals mixed management performance. While some units offer great locations and spacious apartments with decent heating and water pressure, many renters report poor building upkeep, pest infestations, and slow or unresponsive management. Laundry facilities have faced extended downtimes with inadequate communication. Pest control efforts exist but are inconsistent, with several tenants experiencing rodents and bugs. Security concerns tied to neighbors and mail/package theft are noted. Despite some well-kept features and a helpful super in a few buildings, issues with maintenance delays, cleanliness, and owner responsiveness persist, highlighting uneven management quality across the portfolio.

Unresponsive management but amazing location

Pros

Amazing location and great price for size.

Cons

Building not well maintained- carpeted stairs in hallway trap moisture and it smells like mildew. Only 2 washers and one dryer to be shared across 3 buildings make laundry difficult. Had some serious water damage from a leak that took months to finally get addressed. I wasn’t directly responded to by management, even after getting their lawyer involved. I heard about the repairs to MY unit secondhand from my neighbor who had taken them to court previously.
