Ying's place was just as advertised, and is conveniently located close to public transportation and many restaurants/shops. The room we stayed in is closest to the exit and the bathroom, so we never felt like we intruding on Ying's space, and vis versa. Furthermore, the neighborhood felt safe and the neighbors seemed friendly.
Ying goes out of her way to make you and your guests feel welcomed while you stay with her. If there was ever a problem (with the door lock or water temperature, for example), Ying would quickly have it corrected.
We highly recommend staying with Ying if you plan to come to NYC!
