We (2 + toddler) had a great stay at Jodi's place and in Williamsburg. The apartment is located on the very south part of Williamsburg, very close to the Williamsburg Bridge, and super close to the East River Ferry (which is really nice to try!). Subways are also pretty close, Marcy Av (J/Z/M 10 min walk) and Bedford Av (L, 15 min walk) will get you into Manhattan fast.
We liked that Jodi's place is just below the more buzzing heart of Williamsburg, which makes it a bit quieter, but still next door to all you need (very good places to eat, grocery stores, bars, etc.). Check out Teddy's (96 Berry St), good food, and super friendly staff, very attentive to children.
The apt. has a very nice atmosphere, and is pretty well accommodated for all basic needs. Rooftop is a plus in the summer season!
Jodi was a great host, she was there to welcome us and show us the place. Very easy and quick communication and help.
We would definitely come back and recommend this place.
