Jack's apartment was very clean, well-kept, and homey. The decorations were tasteful and not too cluttered. The location was also fantastic; close to the Brooklyn Bridge, Chinatown, great eateries, and a subway station.
Jack was also incredibly communicative and helpful, including sending detailed check-in instructions, and a "tour guide" of good cuisine and things to do in and around his apartment that was very helpful. I would absolutely recommend you stay here.
