Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant reviews of LOUIS KOPLOWITZ-managed buildings reveal mixed management quality. While some buildings offer spacious apartments in convenient locations with pet-friendly policies and decent amenities, many tenants report chronic issues including pest infestations, inconsistent heating, and poor cleanliness in common areas. There is frequent mention of unresponsive or slow management and supers who are often overwhelmed or ineffective, especially regarding repairs and maintenance. Noise and neighbor disturbances are common, and building infrastructure like elevators and water pressure sometimes falter. Tenants advise improved communication, more professional and timely maintenance, and enhanced cleanliness efforts to significantly improve the living experience.

Cons
