Review summary

Summarized from anonymous rental reviews on Openigloo.

Tenant feedback on buildings managed by ADAM GRUSHKO reveals a mixed management reputation. Many appreciate the clean, well-maintained buildings with friendly, responsive staff especially doormen and supers who promptly address issues. Amenities like gyms are valued but sometimes come with additional fees. However, noise and pest control remain challenges in some locations, with roach problems noted and occasional slow management responses. Heating can be inconsistent or overly hot in some units. Complaints about rent hikes and lack of upgrades despite increases appear frequently, alongside a notable isolated report of serious tenant harassment at one property, highlighting variability across buildings managed by this contact.

Illegal Tenant Harassment

Pros

None at all.

Cons

*COURT UPDATE #2* – Landlord Harassment Case We're headed to trial! Landlord's counsel tried filing a gag order to remove this review. Denied. They also attempted to have this case "dismissed without prejudice." Also denied. The judge isn't buying a single one of their arguments. At this point, it's become more than clear with the judge that Steven Nathan (and Stonehenge) hid behind a nonexistent policy to justify their illegal actions. The judge now wants to hear directly from the client, instead of through their counsel. *COURT UPDATE #1* – Landlord Harassment Case Case is still in progress, but so far, the judge has agreed with our position in this matter. They've affirmed that I'm a legal occupant, and they've established that this "so-called" package policy is not even real. Stonehenge attempted to hide behind a fake policy in order to justify their illegal, retaliatory actions. Wild. Read that again. Additionally, the judge affirmed that my fiancée's actions to call the locksmith and replace the locks were entirely lawful. NYC has very clear laws protecting this right as a tenant. There was absolutely nothing in the lease that prohibited her from taking totally reasonable actions given the apartment had just been broken into. *ORIGINAL REVIEW* Beware of Steven Nathan at 10 Downing Street. He *will* break the law and violate your rights as a tenant. I am a lawful occupant of this building. I have lived here for over five months and completed all required move-in paperwork with management. My name is even on the mailbox, and I've been added to the system. None of that mattered to property manager Steven Nathan who insists I'm somehow not a lawful occupant. What?? After a genuine security incident — our apartment door was found wide open and packages gone — management's response was not to help. Instead, they jumped straight to "CYA" mode and attempted to flip the script by accusing me of stealing my own packages. In retaliation, Steven Nathan imposed an unlawful restriction barring me from receiving packages — a restriction his own building staff (doormen & porters) privately admitted they would never enforce. Steven Nathan even confronted me at my door and told me to leave the building solely because my name is not on the lease, and thus, not an occupant. That is not how the law works. New York law explicitly protects occupants like me. What Steven Nathan did has a name: tenant harassment. When my fiancée exercised her legal right to replace the locks after the break-in, Steven Nathan showed up unannounced, stopped the licensed locksmith mid-installation with a false claim that it violated the lease, and promised to complete the work themselves. They never did. Our apartment was left unsecured all day. Deliberately lying about the contents of the lease to make a point is beyond wrong. We now have an active HP Action in Housing Court. Police reports have been filed, including one for harassment against Steven Nathan personally. If you are considering renting here: watch out. Tenant harassment is a real threat here. If you encounter it, don't be afraid to involve the cops and file an HP Action accordingly.

Advice to the owners

Stop breaking the law and harassing tenants.
