Review summary

Summarized from anonymous rental reviews on Openigloo.

Reviews for buildings managed by John Mustac reveal generally well-maintained properties with daily cleaning, strong water pressure, and attentive supers contributing to tenant satisfaction. Many tenants praise the management’s responsiveness and the pleasant living environment in several buildings. However, issues such as occasional heating failures, limited laundry facilities, pest problems like waterbugs, and some noise or problematic neighbors in specific locations have been noted. Garbage management varies, with some complaints about composting access and waste handling. While most renters appreciate the upkeep and friendliness, a few report slow or ineffective owner responses, suggesting room for improvement in communication and maintenance consistency.

Reviews

Former tenant·7 minutes ago

Great maintained buildi

Pros

Cleaned daily. Big apartment sizes.

Cons

Far from train and not a lot of restaurants near by.

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
