Wow. That is hard to describe. First of all, it is incredibly expensive. My husband and I live in a 650 square foot apartment in Chelsea, which is a neighborhood in Manhattan, and we pay $4,000 a month rent. This rent is typical in much of Manhattan, unless you rent in a four story walkup. There are lower rents in Harlem, but that is starting to change.It’s loud. Noise is everywhere. The traffic, beeping horns, the subway trains, sirens, loud people. It takes a while to adapt.Work. It's a hard working city. Many people put in very long hours, whether to make those large corporate and law firm salaries or working three jobs just to get by. It makes the city incredibly busy and focused.Diversity. Well over 800 languages are spoken here, and the dress, habits and food are from almost every world culture. As a gay man, I feel safer here than anywhere I've ever lived.Speaking of safety, NYC is the safest large city in the US and one of the safest large cities in the world. I walk around Manhattan, from Harlem to the Financial District, anytime night or day, and have never felt unsafe.It's a walking city. We don't own cars, and if we can't walk we use the trains. $2.75 and you can go anywhere, even to the beach. I ride trains almost every day. Crowded and not a great system compared to European systems, but it goes everywhere.You entertain out in the city. People do not have friends “over” very often, because apartments are so small. You meet in restaurants, bars, parks, etc.Oh, and the parks. Union Square. Washington Square, little Stuyvesant Park, Madison Square, the list is long and they are wonderful places to stop and rest and be entertained. And of course, Central Park. What's not to like? You can spend a whole Sunday afternoon there walking and eating and going to the zoo and being entertained for free.The weather is changeable, and there is snow in winter and humidity in the summer. But Spring and Fall are delightful. There are flowers everywhere and the breeze off the Hudson River in my neighborhood is sweet.Water. Rivers, beaches, long strolls along the seaport. Seagulls. NYC is surrounded by water.Food. It's the best. From food trucks to fine dining, you can find about everything here.Culture. Incredible museums (MOMA, Natural History, the Met, Whitney… ), you could never see it all. Wonderful small galleries. Opera, symphony, dance. And of course Broadway. Theater is just extraordinary. And the libraries: some are architectural gems as well as storehouses of knowledge.I’ve lived in Charlotte, DC, Philadelphia and several smaller towns. But nothing (in this country) compares to NYC. I retired here (no Florida or resort condo for me), and I wake up every morning feeling incredibly fortunate to live here. And, yes, I do realize this answer is Manhattan-centric. And there are four more exciting and dynamic boroughs (well, maybe Staten Island’s not exciting!). But, it's what I know.A word of advice: don't ever forget the expensive part. It’s best to have a job in hand when you come to live here, and expect to work hard. I am fortunate to be retired, but most people work very hard to live here. Cheers!
