We had a really great time in Edward's and Sarah's apartment. It is much nicer than it looks in the pictures and it had everything we needed during our stay. The bed was comfortable and we slept very well. Sometimes we heard some noises from upstairs (steps, voices), but not loud ones and not very early or late.
A good grocery store and many restaurants as well as a subway station are just around the corner. That makes it really easy and quick to get to Manhattan. For example, it took us just about 30 minutes from leaving the apartment to get to Times Square.
The apartment is slightly below street level and there are windows in the front and the back. As the kitchen is located in the middle, you can not rely on ventilation through a window while cooking. However, there is a fan and an exhaust hood to turn on for ventilation.
Communication with Sarah and Edward prior to and during our stay was uncomplicated, as was checking in and out. They made us feel very welcome. For example, when we arrived they had bought groceries for our first breakfast. They also told us about the neighborhood, things to do, etc. and put many flyers, magazines, and maps in the apartment.
We will definitely stay here again on our next trip to NYC!
