Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback for buildings managed by Magdalena Kosz is mixed, reflecting variability in property conditions and management responsiveness. Some buildings boast clean, well-maintained spaces with friendly superintendents and good water pressure. However, others suffer from serious issues including pest infestations, inconsistent heating, and aging infrastructure. Management responsiveness ranges from timely and helpful to slow and unresponsive, especially concerning pest and heating complaints. Residents advise improvements in heating, pest control, and cleanliness, alongside better communication from management. Overall, tenants should expect disparities in maintenance quality and responsiveness depending on the specific building under Magdalena Kosz's oversight.

Reviews

Former tenant·36 minutes ago

Overall great place

Pros

Super is great and friendly

Cons

Heating can be consistent

Former tenant·10 minutes ago

Avoid living in this nightmare building

Pros

Accesible transportation, centric and beautiful area.

Cons

Rat-infested, management had an attitude, no heating, an old kitchen, the moldings were collapsing, so was the staircase to the actual building and the manager and his workers sexually harassed women. Not even mentioning the fact, that the real estate agent was rude and condescending.
