To Yolanda's house is a 10 minute-walk from 85 St - Forest Pkwy station. It takes about an hour or so by subway from the JFK airport. If you carry heavy or lots of luggage, taking a taxi from the airport is recommended since there is no elevator you can use at the station.
The neighborhood is safe to get around and has many useful stores. Yolanda was very kind and welcoming. :) The room was clean and neatly arranged, and the bed was comfy. She and her family gave much space for me. I really liked staying there. I strongly recommend this accommodation if you don't mind an hour-long commute to and from Manhattan.
