We had a great time at the house. We brought our kids, 8 and 5 and it was a fun home-base for their first time in New York. Definitely far uptown but the metro was super easy to jump on and when we wanted to stay close to the house and not take the 5 year old on epic, NY-style walks, there was plenty to do right around the house.
The house was clean and well appointed with a great home-y feel. There are a lot of stairs in the house (as advertised) but it was nice to have the bedrooms upstairs from the kitchen and living room. The neighborhood was quite loud in the evenings (between 9pm and 1am), especially from the master and guest rooms but the kids room being at the back of the house kept it quiet for them.
Our host was beyond helpful and kind. All in all a great place to stay!
