Nadine's place was perfect for our month-long stay. It's located in near a number of restaurants and bodegas and not too far from the A/C and J/Z trains, which take you into Williamsburg, Downtown Brooklyn and Manhattan in 20 minutes. The neighborhood is very residential and relatively quiet.
The space itself is large and comfortable in a walk-up building. There's an office space and a room separate from the rest of the space, which is very helpful if you need to take calls or work. The kitchen is relatively small but well-equipped. The building gets cold relatively easily (it wasn't cold enough that we tried to set up heating).
Nadine was very helpful and check-in was a breeze. There are a number of recommendations for restaurants on a board and Nadine was very responsive whenever we had a question.
Overall I'd gladly stay at her place again and I highly recommend it if you want to stay in a quiet area but still be well connected to more touristy and hip locations!
