We stayed at this apartment with our 5-year-old daughter for three months while our place nearby was renovated. It's very comfortable, and steps from a Walgreens, a good bodega with great Middle Eastern food, and a good supermarket. And it's a pretty short walk to all the restaurants, bars and shops on Prospect Park West, and of course to the park. The apartment is facing the highway, so there is some ambient noise, but it's not bad at all. Parking is shockingly easy for NYC. The neighbors are friendly.
The apartment itself is comfortable and well-laid out. The kitchen is well stocked. Our daughter enjoyed the little workspace downstairs. There is laundry in the building, but it's shared with other tenants so you may have to wait your turn.
The hosts are also very responsive. Any issues we had--we were there for several months so some small things inevitably turn up--were very promptly addressed. We recommend it.
