Former tenant·3 minutes ago

Pretty Standard Living

Pros

attached to a grocery store, gym was small but manageable, neighbors were kind or kept to themselves. Management was responsive when roof began leaking. No real issues

Cons

Trash would pile up on weekends but no bugs/rodent (thankfully)

Former tenant·10 months ago

It’s all a facade

Pros

My apartment is nice and the building amenities are seemingly nice.

Cons

Neighbors are disgusting, don’t know how to just a trash chute, constantly dealing with roaches. The rooftop is absolutely disgusting and unusable— tenants are constantly taking their animals up there to defecate. I had literal mold and roaches coming OUT OF MY AC UNIT. Building management is VERY SLOW to respond to any requests, they starting being responsive once I involved 311. Rent is too damn high, and the garage rate is insane.

Advice to the owners

Actually give a shit about the building and the people who live here; enforce lease rules, how about actually utilizing the cameras in the building?
