Review summary

Summarized from anonymous rental reviews on Openigloo.

Recent reviews for buildings managed by MPI C/O OLSHAN PROPERTIES paint a mixed picture. While some tenants express satisfaction with the building's location, friendly staff, and well-maintained amenities, persistent issues with pest control, cleanliness, and heat management overshadow these positives for many residents. Consensus suggests significant concerns regarding management responsiveness and overall integrity, particularly in cases involving maintenance and safety issues. Renters recommend addressing pest control more thoughtfully and improving communication from management. Overall, potential tenants should be cautious and weigh these factors heavily as they consider leasing within these buildings.

Hazardous Lead Levels Undisclosed

Pros

Site staff are friendly. Building is cute, if aging.

Cons

They shut the heat off in the winter from 1am-5am to evade HPD detection . Numerous tenants complain of roaches. Building management is absolutely unresponsive and without conscience. Many tenants just recently discovered Olshan provided fake lead disclosures to us dating back to at least 2022, saying no lead paint, when in fact units had toxic and hazardous lead paint levels, in excess of 10 TIMES THE SAFE LEVEL. This includes in units where there were pregnant women, infants, and vulnerable tenants. When confronted they took no responsibility for the fraud and matter had to be escalated to the EPA and I believe the OAG. Matter is still ongoing. The most duplicitous and deceitful human beings we've ever dealt with. It's genuinely shocking.

Advice to the owners

Integrity and honesty is always more lucrative in the long run, is what I'd tell management. Leasing secretary Canny Castillo was caught with absolute proof falsifying lead disclosures across many years and multiple tenants and threatening those tenants when they found out and yet she has, to date, inexplicably not been fired. And we can't fathom how anyone can navigate around their conscience to put children and babies in perhaps irreparable danger, as they have. This also goes for the danger they put their own workers and contractors in, whom they also apparently have hid known lead hazards from, which should be a catastrophic workers comp liability.
