I really enjoyed staying there. It is located in the center of willamsburg, which means lots of super nice restaurants and cafes are very close. The subway station was close, and you can get to the union square in 3 stops. Christina let me check in early in the morning. I didn't have many chances to come across her, but she is the best host for independent travellers.
In addition, the house is clean and tidy. The room was relatively small, but it was comfortable and the view from the window was very nice.
