Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent tenant feedback on buildings managed by Moshe Blum reveals mixed experiences. Some residents commend the amenities like rooftop access and gym, along with generally decent neighbors and quiet surroundings in certain units. However, there are significant concerns about management responsiveness and maintenance quality, with reports of unaddressed issues such as leaking repairs done poorly and poor heating insulation leading to uncomfortable winters. Safety concerns in the surrounding area have also been noted, along with problems like package theft and inconsistent garbage management. Tenants urge the management to improve communication, maintenance, and building security to enhance overall living conditions.

Reviews

Former tenant·11 minutes ago

Avoid at all cost

Pros

Good central heating

Cons

Frequent drug addicts hang out on the doorstep, often abusive and threatening. Guests and visitors often did not feel safe walking back to the building at night. A significantly rougher area than it appears on first glance. Parental payments are made through an app that is at times unusable and provides no evidence of payment at all, leaving the renter in the dark and without evidence of payment history.

Cons

new management became less responsive, fixing things don’t always replace with equal or better equipment
