What is the difference between North Slope and South Slope?

North Slope generally refers to the blocks above roughly Ninth Street, closer to Grand Army Plaza, Barclays Center, and the 2, 3, B, and Q trains. It holds much of the neighborhood's grandest pre-war housing and commands the highest prices. South Slope, below Ninth Street toward Prospect Avenue, offers a more varied housing mix, a slightly more relaxed feel, and relatively more accessible price points, served by the F and G lines. Both are firmly Park Slope; the difference comes down to price, housing type, and which trains are at your door.
