Where Did Barry Live?

Back in 2008, the Obama campaign confirmed that President Obama once lived in Park Slope:

The Obama campaign declined to discuss Obama's time at Columbia and his friendships in general. It won't, for example, release his transcript or name his friends. It did, however, list five locations where Obama lived during his four years here: three on Manhattan's Upper West Side and two in Brooklyn — one in Park Slope, the other in Brooklyn Heights. -"Old Friends Recall Obama's College Years"

And the founder of a local campaign support organization recounts a conversation she had with candidate Obama after the Democratic primary:

Gabriele Sewtz, co-founder of Audacity of Park Slope, spoke to Barack Obama briefly after the event. Gabriele, who had met Barack Obama on previous occasions, was proud to report that thanks to the tireless efforts of Audacity of Park Slope, Barack Obama had won Park Slope with 56% on Super Tuesday. And Barack Obama answered with a smile: "I used to live in Park Slope". -Audacity of Park Slope

We're not aware of any other President who actually lived here, so this is pretty cool... does anyone know where Barack Obama lived in Park Slope?
