I apologize for the delay in getting back to you.
Anyway, I have been living in New York City for 32 years now and I really do love this town. Also, I live in a section of the Manhattan borough of the city that is called Spanish Harlem or El Barrio and, in my opinion, it is one of the hippest neighborhoods in the world. In fact, if you have not seen it already, take a look at my hub entitled, "There Ain't No Recession In My Neighborhood" and that will give you an idea of what my community is all about.
And yes, NYC, Mahhattan anyway, is always fast paced and it is known as the "city that never sleeps." Also, it is quite expensive to live here, largely because the rents for the apartments are very high. However, many young people who move to the city get around that by sharing apartments.
Also, there are a lot of exciting, entertaining and educational things to do here. There is "Broadway" and other live theater, plenty of real cool night clubs, numerous museums, concert halls, beautiful parks, terrific restaurants of all types, and loads-and-loads of very interesting and nice people.
I hope you get the chance to visit here some day, and if you do, be sure to let me know. I will be happy to welcome you here and to show you a few of the sites :-)
