Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews of buildings managed by Ari Mossberg indicate a mixed management experience. Tenants often praise well-maintained lobbies, spacious units, and dedicated superintendents who work hard to assist residents. However, concerns arise regarding management's slow responsiveness to maintenance issues, particularly persistent heating, gas leaks, and water damage problems that sometimes take weeks to resolve. Pest control is inconsistent, with some buildings facing significant issues. Security is another frequent complaint, with recurring package theft and building access concerns. While some appreciate affordable rent and decent locations, others report feeling the management cuts corners, leading to tenant dissatisfaction. Overall, expect attentive on-site staff but varied responsiveness from management.

Reviews

Former tenant·5 minutes ago

Management company grabbed my deposit money

Pros

The lobby is well maintained. The plants in the hallways of each stair adds color to the building. Flights of stairs are very short.

Cons

The elevator is haunted and will skip certain floors randomly. The stairs are very steep. The management company delayed 3 weeks over, then falsely accused us of damaging the hallway and elevator with no proof. They withheld our entire security deposit showing no evidence of the cost of the "damage".

Not the best

Pros

There’s an elevator in building and laundry in building.

Cons

Horrible pest problem and packages get stolen on a regular basis.
