Rachel's place is very reasonably priced for Brooklyn/New York. You can tell that a lot of work has been put into making the flat feel welcoming and cosy. It seems to be newly decorated etc. The shower is good, although if you are over 5"10 you will hit your head, not a problem for us though.
It is not the nicest part of Brooklyn if you are hoping to be near all of the gentrified aspects then this may not be the best spot. It is about ten minutes walk to metro stations which will take you to most places in Brooklyn or Manhattan.
Rachel was easy to contact and even though we never met, I did talk to her on the phone and she was very nice and helpful.
