KIM (KEEP IT MOVING) BAD building

Pros

- It's historic to Black history as Duke Ellington lived here (hence the building's name). - My apartment is a real apartment, very spaciaous. - Diverse building with people of all nationalities & ethnicities.

Cons

- Rat infestation. - Roach infestation. - Dirty hallways. - Broken elevator (currently out for the next 3 months). - Dirty laundry room area filled with rats. - Lazy super. He drives UBER more than he cleans the building. - A LOT OF DRUG ADDICTS IN THE BUILDING. A woman is squatting below me smoking CRACK & management has done nothing about it. - A LOT OF RACIST white people live here as well. - Buzzer is/was constantly broken. - Building's door is constantly broken. - Packages get stolen. - I had a drug addicted neighbor attack me. - Other tenants pretend that they don't live in the same building & face the same problems. Ignoring the issues in the building.

Advice to the owners

No advice. They likely know who this is if one of their minions decides to even read something like this. Mark Scharfman is the owner. Look him up, he's areal dirtbag slum lord.

You'll be Ignored and then blamed for not informing them

Pros

The units are large including the hallways and bedrooms in the apartments themselves. The trash is well maintained which is nice especially since you pass it every time you do laundry. Elevator in building but only one so you can wait a while occasionally. Very close to the C train!

Cons

Beach Lane management will ignore your calls and emails. We had bed bugs for almost a year and forced us to move out since it was never resolved. Upon the initial complaint, they did respond well by sending an exterminator (who sucked at their job too) but after that they did not stay on top of the bed bug problem. They kept saying they already sent an exterminator and it is likely our fault for countless reasons they tried to put back on us. Then when I followed up again about the on-going issue and the health and safety concerns from the on-going situation, they blamed us for not telling them sooner despite them emailing us and directly informing us not to write them any longer until they have an update for us - this was a 3-week gap in a 7 month period at this point. Called 311 multiple times and that was a process itself but when 311 reported other issues, beach lane attended to this since there were fines involved. But attention to the bed bugs still. They claimed they inspected the other units but they did not! I checked in with each neighbor and no one ever inspected their units or told them. Guess what. We found them in other units. This experience can go on but the lack of care for tenants from Beach Lane I found to be true as I dealt with them while living here briefly.
