The NYT wrote up a decent article a couple of years ago (you may be prompted to login to get past their toll-gate paywall). If you look at the slideshow, the photo of the A train stop at 181st is near where I live.
I live in the area referred to in the article as Hudson Heights; it's basically where middle-class white people live, as opposed t the rest of Washington Heights, which is still mostly working-class Hispanic. Because I like the idea of living in or near a culture not my own. I prefer Washington Heights, and expect to make some forays into the neighborhood east of Broadway.
I like my building. It doesn't look like much from the outside. It's near the GWB, which is odd. However, I overlook an interior courtyard, so it's quiet, and I can step out of the building easily to a beautiful view of the Hudson river.
It's 500sf, a small 1 BR with a narrow living room and a galley kitchen. Pictures soon, promise.
My plan is to fix up the baseboards, paint, and move in by the end of the month.
