My family and I spent a month at Eleanors place in July and we absolutely loved it! Its so close to the subway (F,G, R) which makes it easy to get from Park Slope to Manhattan, central Brooklyn, Coney Island and so on. The apartment is in a calm and safe area that is very close to grocery stores, pharmacies, and restaurants. The apartment in it self has all you need for a good stay.
If you are staying with kids, there are several playgrounds in the area and two public swinging pools (Red Hook and Boerum Hill). If you want to go to the beach, just take the bus (B61) to Red Hook Cruising terminal and take the NYC Ferry to the Rockaways or the subway (R, N) to Coney Island.
Eleanor is a fantastic host and a delight to talk to. It is easy to get a quick response if you have questions regarding your stay either thru the Airbnb app or other apps. I would gladly stay here on my next trip to New York, and I highly recommend other to stay here if you get the chance.
