I had a wonderful time at Diana's place. She had to head out of town last minute so I was greeted by her daughter, given the full tour and instructions for the place. I had the full upstairs to myself - the bed was very comfortable, room was spacious, nice and bright. The house is a bit of a walk from the closest subway station so with luggage it might have been easier to taxi but once settled, it was actually a nice walk to get to the station.
All in all I had a great stay and would definitely recommend this place if Park Slope is your destination.
