only complaint was I couldn't stay longer.
this is a great apartment on a quiet street in the Carroll Gardens neighborhood. the elevated subway runs behind the house, but with the windows closed it sounds like distant thunder and we didn't find it disturbing. Garbage day is Monday, so there is traffic noise that day, otherwise very little.
if the weather is nice, sit out on the stoop. if the neighborhood kids are playing games, they might invite you to join in (but trust me, you'll probably lose as badly as I did).
