Approx 10 min walk to the blue metro lines A&C straight to Manhattan. These also take you straight to YFK airport, so perfect. The green line is also on walkable distance (approx 15 min) to take you to bowling Green or Grand Central.
Neighborhood is safe (also at night) and there are grocery shops close for buying a breakfast. Appartement is spacious, but wouldn't recommend it to spend the evening to relax and hangout as the sofa is relatively small and same goed for chairs.
Overall definitely recommended for a city trip with good connections to Manhattan!
