Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback on buildings managed by WILLIAM DEMOS reveals mixed experiences with management responsiveness and pest control. While many renters commend the attentive superintendents and appreciate the quiet, friendly neighborly atmosphere, persistent cockroach and rodent issues in some Queens properties indicate that pest problems are not consistently addressed. In Manhattan, residents value the convenient locations and generally responsive management, though some report safety concerns and occasional neglect in maintenance or communication. Garbage management and cleanliness receive varied ratings, reflecting inconsistency across buildings. Overall, tenants advise more proactive pest control and improved communication to enhance living conditions.

Reviews

Former tenant·8 months ago

Bad roach problem

Pros

Nice apartment besides roach problem

Cons

Didn't fix roach problem

Advice to the owners

Fix bug problem

Former tenant·9 months ago

Horrible Roach Problem

Pros

Great location. Good lighting in apartment.

Cons

Apt 1C has a terrible roach problem and management did very little to get to the source of the issue. We would see around 15+ roaches a day and ended up moving because of it.

Advice to the owners

Extermination in the apartment is not enough. Get the source of the infestation in the basement.
