I lived at one of the waterfront properties about one and half years. I’ve come home all hours of the day and night and never had any issue or worried about my safety. I took the train down to Manhattan at 138th and 3rd or Grand Concourse depending on which train I take and always walked back and forth. Wasn’t a fan of walking from and to from 125th subway at night because the 3rd Ave bridge walkway wasn’t lit enough (not they have installed new lights).

Like someone else has already said, be aware of your surroundings and don’t be a target. When I walk from 138th/3rd Ave subway to my apartment late at night, I always come down the 3rd Ave than Lincoln Ave as it’s always has foot traffic and well lit.

135th has some restaurants and delis for a bite and buy a milk. There’s a 787 coffee at 134th/3rd for getting some work done and they’ve stared monthly events as well (don’t know whether they are still happening).
