Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews for buildings managed by Magdalena Kosz reveal a mixed tenant experience. Many appreciate responsive and helpful supers, generally clean buildings, and good locations. Amenities and quiet neighborhoods are commonly praised, with tenants noting friendly neighbors and fair management communication. However, persistent issues include pest infestations, noise from nearby nightlife, and inconsistent heating or water pressure. Significant concerns arise in some properties with poor maintenance, security vulnerabilities, long unresolved repairs, and even hazardous conditions post-fire incidents. While some buildings maintain solid standards, others suffer from neglect and management unresponsiveness, suggesting variability in care across Magdalena Kosz's portfolio.

Reviews

Former tenant·4 months ago

Good enough place

Pros

Super is very helpful, neighbors are friendly

Cons

Facade maintenance has been going for over a year, only entrance is through the side door where trash is stacked before it goes outside and it can start to smell very bad as it sits there for a few days sometimes

Would not recommend

Pros

Management was responsive and resolved our issues. Location is close to trains, grocery store, bars/restaurants/shopping. Maintenance came by often to take out trash and clean the hallways.

Cons

Very noisy street - there are always people sitting on the steps of the building and the noise is even worse on the weekends as the building is right above a club (lots of fights break out and I witnessed someone die from an overdose on the front steps). Building is not secure - there is only one door at the entrance, which is unnerving. I had multiple instances of packages being stolen out of the building. Management installed a locked package room under the stairs which has helped reduce the thefts but it is still scary that people can get into the building so easily. Pests - I saw multiple rats in the first-floor hallway where management told us to put our trash. We also had cockroaches in our third-floor unit - baby ones that will likely become a bigger problem. Leaks/appliance issues - I moved in at a time when my unit and those around me were in the process of being renovated or had just been finished, so there were many kinks to work out (hot water in bathroom didn't work, radiator leak, leak through the ceiling from the unit being renovated above, stove not working, internet cables not ready for use). The management company was very responsive when these issues arose and took off some money from our rent, but it was very inconvenient and uncomfortable.

Advice to the owners

Keep being responsive and look into long term solutions for building security and pests
