We've stayed for two weeks in Libby's flat. Very nice, spacious flat - it is bigger than the impression you get from the pictures.
It takes about 40 minutes to take to Manhattan - a bit quicker when you figure out how to catch an "express" trains. The immediate neighbourhood looked a bit rough - my first impression. But just a couple of streets up, very nice area with GREAT places for coffee, breakfast and a pint. And after two weeks I just loved "our" street as well!
We enjoyed our stay and I would definitely recommend it.
