Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback for buildings managed by John Mustac reveals a mixed management experience. Many appreciate the cleanliness and the attentiveness of the superintendents, highlighting responsive and kind staff who maintain the buildings well. However, tenant concerns persist regarding inconsistent owner responsiveness, noise issues, and problematic neighbors, which sometimes go unaddressed. Heating and hot water reliability is also an issue in some locations, along with pest presence linked to infrastructure vulnerabilities. Garbage management varies by building, and limited amenities such as laundry and roof access are noted. Overall, while some tenants commend the management, others advise improving communication and addressing neighborhood disturbances more proactively.

Reviews

Former tenant·Over 1 year ago

Nice building but useless management

Pros

Super is great, kind and keeps the building very clean.

Cons

SO many loud people, people smoking in apts, people siphoning mysterious liquids out their windows???? Management pretends to care at first but then will stop replying to you.

Advice to the owners

When a tenant alerts you about neighbors causing damage to their unit (and the tenants unit) perhaps you should reply

Former tenant·Over 1 year ago

Very pleasant living experience

Pros

Good amount of space, a nice view from the windows, floors aren’t the kind where you can hear every footstep of the person above you. First apartment I’ve lived in where I haven’t had to worry about a seemingly endless list of issues.

Cons

No laundry, no roof access. I go to the roof floor and look out the window at the roof…so close yet so far…if there was one thing I could change it’d definitely be allowing roof access, but I’m not sure its possible with some of the equipment they have up there.

Advice to the owners

If allowed on the roof I will assume all liability and then some for radiation poisoning, accidental injuries, and anything else that could conceivably occur as I hang out politely on the roof. :)
