Former tenant·2 minutes ago

Mediocre experience, watch out for pest issues

Pros

-Location was close to the subway and to buses, and not that far from Central Park North -Super was nice and helpful

Cons

-Had cockroach and mice issues which I had to call an exterminator to fix. -Often very noisy neighbors, and building was once under lockdown due to a dangerous presence on one of the upper floors.

Big apartments shady occurrences

Pros

Natural lighting Spacious Laundry room

Cons

My apartment was broken into a few years ago and the security cameras “didn’t have footage available” when the cops showed up. I suspect it was an inside job
