With the long-awaited arrival of the Second Avenue subway, Yorkville has become the best of both worlds -- a slightly off-the-beaten-path enclave with zippy Manhattan train access. The cozy Upper East Side neighborhood between East Harlem and East 79th Street has also seen an influx of kid-friendly amenities, like new restaurants and play spots, adding to the established old-time favorites, wonderful parks, and great schools.

To meet the demand, beautiful new luxury buildings, like Citizen360, offer zen-inspired design, envy-inducing views, spacious apartments and a long list of top-notch features — think relaxing residents' lounges and private entertaining suites, yoga studios, infrared saunas, and stress-free on-site parking. Surprisingly, with so much going for the neighborhood, apartments still go for less than Manhattan averages, making Yorkville a smart choice for families looking to have it all.

Sure, your cozy fourth-floor walk-up or historic, buckling-at-the-foundation brownstone has a certain amount of New York charm, but when you add kids to the mix, charm doesn't always cut it in this city. From steep stoops, to sub-par schools, to a sheer lack of space, there are plenty of not-so-family-friendly hurdles that never even cross your mind when you sign on for a pre-parenthood apartment.

(Oh, and, surprise, surprise, 111 Murray Street actually has them all...).
