Other than the caricatures of cultural stereotypes, High Maintenance is the most accurate of the TV shows I've watched that take place in NYC. The main character bikes around and enjoy all parts of the city and has random interactions with all kinds of people.

The part that is most accurate in the show is showing how people use public space eg parks and plazas etc. That aspect is missing so much from TV and movies because enjoying public space all the time is impossible if you live a car dependent life ie what most people know as living.
