Super close to the subway station, literally 3 or 4 houses away. No problems with next door, walls seem thin so you can hear them walking around but it was not a problem at all after 9pm. Don't be wary of the area in Brooklyn this location is at, the local convenience store has kind employees and the people mind their own. I would recommend staying here if you plan on being on the subway daily, very straightforward to figure out and the A/C train lines will get you where you want to be, or you'll only have to change trains once to get elsewhere.
