We had a great stay in this apartment for a week in December 2014: two adults and two teenage daughters who shared the second double bed. There are no bedroom doors, only curtains, but that didn't bother us as we all went to bed around the same time.
The apartment was exactly as described, and our host Ruby easy to contact. She met us on time at the apartment to let us in.
It's up four flights of stairs, but worth it.
It is located on the F train line, only a short distance from 2nd Avenue station.
The beds were very comfortable, and the bedlinen and towels were large, clean and plentiful.
The apartment is spacious with large windows.
Heating was good.
The kitchen and bathroom are good, well fitted out. Really good shower. A microwave oven would have been a useful addition to the kitchen.
Only other comment is some additional lighting would make the apartment a little brighter at night.
