Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews for buildings managed by 21 ADELPHI ST LLC reveal mixed experiences. While the management and super are often noted as responsive and understanding, significant issues persist with cleanliness and pest control, particularly roach infestations. Tenants frequently mention poor sound insulation and noisy neighbors, contributing to discomfort. Heating problems and safety concerns, including reports of electrical fires, have also been raised. Garbage management shows some improvement, but overall building upkeep and communication during crises need enhancement. Prospective renters can expect affordable units in an emerging neighborhood but should be prepared for challenges with maintenance and noise.

Former tenant·Over 3 years ago

Decent building, roach infestation

Pros

responsive management and super. maintenance issues were treated seriously.

Cons

terrible roach infestation and landlord was unhelpful. Building echos noise. My upstairs neighbors 7am alarm would wake me up often. Walls are hollow completely, the building lacks any sort of insulation. Brick wall was not sealed and shed dust and small rocks constantly. brick was also dirty. Landlord was unhelpful

Advice to the owners

be mindful of cleanliness, roaches are an issue.
