Nice building and management but loud street

Pros

Management cleans often and is response. Units are well cared for.

Cons

Street noise is incredibly oppressive all times of year. Neighbors can be very loud in building. Some mail and package issues with theft but has resolved.

WORST MANAGEMENT EVER – TOTAL NIGHTMARE

Pros

Unfortunately there were none.

Cons

DO NOT RENT FROM THIS MANAGEMENT COMPANY – A TOTAL NIGHTMARE If I could give zero stars, I would. When I first moved in, I was excited to work with this management company, but they quickly became my worst nightmare. The owner, Tommy, is a complete joke—he doesn’t care about tenant safety, building conditions, or enforcing any rules. The only thing he cares about is taking home a paycheck while ignoring the disasters happening in his buildings. I thought a management company’s job was to ensure tenants have a safe and livable home, but Tommy has made it clear that’s not his priority. His properties are completely neglected—Sanitation fine stickers are slapped on the front door DAILY because of how disgusting and unkept the building exterior is. Inside, it’s even worse. Overcrowded apartments, with families of eight crammed into a one-bedroom, tenants smoking in the hallways, constant noise, package theft, and even physical and verbal harassment go unchecked. There’s currently a petition circulating to have a tenant removed because they’ve harassed multiple people and flooded the floor, but Tommy? He’s sitting at home, in his peaceful, quiet house, twiddling his thumbs, completely unbothered. The noise in my unit was out of this world because instead of properly fixing a collapsing ceiling, they just slapped some plywood and a 1-inch piece of drywall over it, to get a extra $150 on a renovated rent stabilized unit —which only amplified the noise, not to mention it’s completely against the NYC DOB regulations for a damaged structure. To make matters worse, rather than addressing the fact that a family of eight people was jammed into a one-bedroom unit, running laps and banging beyond quiet hours with clear evidence proving it, Tommy chose to gaslight me and act like I was just “sensitive” to noise. Instead of acknowledging reality and enforcing basic living standards, he decided I was the problem for expecting a livable space. Tommy even had the audacity to claim that I gave him PTSD—a completely ignorant and laughable statement that proves his lack of education and professionalism. Tommy’s complete lack of professionalism and regard for tenant wellbeing is astonishing. His buildings are an absolute disaster, and he is more interested in opening failed restaurants than taking care of the properties under his management. He will not address your concerns, ignore safety violations, and make excuses rather than take responsibility. The tenants are left to fend for themselves in conditions that are not only inhabitable, but completely inhumane. This company is a disgrace. If you value your sanity, safety, and basic quality of life, stay far, far away. Tommy does not care about his tenants, his properties, or anything other than collecting rent while doing the bare minimum. Rent here at your own risk.

Advice to the owners

Try opening another restaurant instead of ruining tenants lives
