I lived in Sunset Park 4-5 years ago. Great apartments to be had out there. The closer you can get to the 36th St. subway stop, the better transportation options you'll have as it's both a local and express stop. There's also a great Chinatown up towards 7th Ave that has some great Dim Sum out there. Whatever you do, don't live on 5th Ave...one of the loudest places in Brooklyn.
