Decent management but poorly maintained

Apartments are not maintained unless you complain

Former tenant·14 hours ago

Great landlord, Great location. Noisy street.

Pros

Landlord takes great care of the building and is very responsive. Super location in Park slope near grand Army Plaza, and close to trains.

Cons

Only downside is that Union Street has a lot of traffic and is noisy so I’d recommend an apartment in the back of this building
