Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenants under Michael Grunstein appreciate his responsiveness and reasonable management, particularly in addressing urgent concerns and maintaining overall building operations. However, issues with cleanliness, pest control, and maintenance—especially in older walk-up buildings—have been noted. Residents call for improved superintendent performance and greater transparency in financial matters such as security deposit deductions. Noise levels can be problematic near busy streets or construction sites, impacting comfort. While some buildings are well-located with desirable amenities, a need for better upkeep of common areas and interior repairs remains. Prospective renters should expect attentive ownership but also be prepared for some aging infrastructure challenges.

Reviews

Former tenant·5 minutes ago

Great space and landlord but very noisy

Pros

Lots of natural light all rooms are decently sized with windows large living room/kitchen space Landlord is very responsive to all concerns

Cons

Construction happening next door for the last year which makes it very loud. Also a lot of noise from the street in the front area of the house. walk-up building no dishwasher

Former tenant·10 months ago

Great landlord, awful super

Pros

Laundry in the building, and the location is great for eating out and going out

Cons

The super will ignore you, even if you’re having an urgent issue. The common areas are barely cleaned. Because it’s an old walk up, you will encounter a mouse every so often.

Advice to the owners

Make the super do their job
