Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenants of buildings managed by Magdalena Kosz appreciate the convenient locations and some recent unit renovations. However, recurring pest issues, notably mice and cockroaches, have been a significant concern, with complaints about slow or insufficient responses from management and the superintendent. Garbage management and cleanliness receive mixed feedback, while heating and water pressure are sometimes reported as inadequate. Although neighbors and noise levels are generally rated positively, renters advise management to take tenant concerns more seriously and improve maintenance responsiveness. Overall, expect well-situated buildings with common pest and maintenance challenges, alongside varied management attentiveness.

Reviews

Former tenant·Over 1 year ago

Had mice problems

Pros

Great area, pretty well maintained for EV, new renovations and we really loved our unit

Cons

We had a mice infestation after our first year. Super was not super helpful

Former tenant·Over 2 years ago

Good location, beware mice

Pros

Our appliances are reasonably updated, and the bathroom is fairly nice. Really good location for EV. Mud coffee is right there, along with other vintage stores. Convenient to subway line.

Cons

After about ~24 hours in the apt we realized we had a mice infestation. Landlord refused to bring in an exterminator, only gave us sticky traps. We killed/trapped 7 mice over the course of 3 days. And there were many more. Eventually we reached prop management and they sent someone over to fill in cracks (as we initially requested months earlier). All sorted now but took 3 months and felt like hell living in a place with that severe of a rodent problem. Should be fine living here now, but mice will likely eat through the foam sealant eventually.

Advice to the owners
