Review summary

Summarized from anonymous rental reviews on Openigloo.

Reviews for buildings managed by Kostas Zachariadis reveal a wide variance in tenant experiences. While some buildings are praised for cleanliness, effective pest control, and responsive management, several others suffer from severe neglect including poor maintenance, inadequate heating, pest infestations, and garbage problems. Notably, some properties reportedly face safety and noise disturbances with little intervention from management.

Prospective renters should expect inconsistent upkeep and responsiveness across different buildings, indicating that management oversight may be uneven and improvements are needed to ensure a uniformly livable environment.

WORST MANAGEMENT AND PROPERTY MAINTENANCE

Pros

Location is. Great

Cons

Where do I begin!?! The building is filthy, hasn’t been cleaned in almost a decade. Trash is piled in the entry , no heat in the winter, poor water pressure when someone runs the water in another unit, holes in the ceilings and along the floors, cracked tiles because they did a horrible renovation after the building caught on fire, they keep trying to push the rent controlled tenants out, nothing is ever fixed properly and the landlord doesn’t do anything to improve the living conditions.

no major complaints, aside from a former noisy neighbor. occasional noise from the bar downstairs but very manageable, especially in winter months when outdoor dining is less active.
