Myself and my family stayed at Nancy's for 4 nights and we had a great time. The apartment has everything you need and Nancy was very helpful and quick to answer any questions we had.
The location may not be to everyone's taste but we didn't have a problem. We were out early in the morning and not back until late so not staying in the city didn't bother us. It's a 15 minute walk to Kosciusko St station (I would recommend using this station and walking up Patchen Ave as opposed to using the Myrtle Ave station), from here it's a 15/20 minute journey on the J Train to Downtown Manhattan or you can change to the M Train at Mrytle for a 25 minute journey to Times Square, ESB, Rockfeller, etc.
