Reviews

Former tenant·Over 2 years ago

Worst place to live. BEWARE!!!

Pros

Nothing. Nothing. Nothing at all.

Cons

Poor management, noisy neighbors, package thieves, large amount of drug/substance abusers, roaches, mice, broken elevators, power outages, thin walls, vehicles are constantly broken into in the garage, surrounding neighborhoods are consumed with violent crime, two fare zone (Uber is your expensive best friend), no parking after 7pm

Advice to the owners

You know better, but rather choose not to do better. You need to be investigated by the state and city considering that this building falls under HPD stipulations. You need to be brought up on federal charges. In due time!
