Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenant reviews of buildings managed by William Demos reveal a mixed management record. Several buildings are praised for responsive supers, good location, and classic architecture, with residents appreciating cleanliness and quiet neighbors in some cases. However, recurring issues include pest infestations (cockroaches, rodents, bedbugs), inconsistent maintenance, elevator problems, and slow or lacking owner responsiveness, especially in older or larger properties. Complaints emphasize neglected common areas, security concerns, noise disturbances, and outdated infrastructure. While some tenants approve of the management, many urge for improved pest control, transparency, and building upkeep to enhance living conditions. Prospective renters should weigh these factors across specific buildings.

That being said it is a prewar building and has its issues. Sometimes too hot. Sometimes pest!
