This is a fantastic and spacious one bedroom apartment. The F and G lines are right at the end of the street (easy 2 minute walk, even with luggage), ready to take you all over town. That said, the Cobble Hill/Carroll Park area has everything you need within walking distance - you might never need to leave! 30 minute walk gets you to Prospect Park, even less will get you to the promenade to walk along the piers and river.
The apartment is surprisingly spacious for NYC, and everything is brand new and modern. We visited during the summer but were amazed by the heated floors in the bathroom. Plenty of light in the living room from the backyard too.
