We can't speak highly enough of our time at Yair's apartment.
The location is fantastic - especially if you're travelling with kids. Park Slope is geared up for a family-friends NY experience. The apartment is super close to the Subway station (F & G trains) which makes getting around Brooklyn and into Manhattan easy. There are loads of food options, if you want to eat out and if you prefer to cook at home then the kitchen is great and there are great food stores in walking distance.
We honestly had the best time in Brooklyn and we wouldn't hesitate to stay at Yair's again or recommend to friends/family travelling to NY.
