My sister and I stayed at Chris's place on December 2017. The host family is friendly and kind, ie they made sure we had clean sheets and offered to give us a ride to the metro. The check-in process was also stress-free and quick to respond. You are also given an extra spare key so you can access the room without disturbing the family if you're going home late.
The room is very comfortable-- there's an extra portable heater, there's plenty of blankets, and the room felt very clean. The walls are filled with beautiful pieces of artwork (made by the wife) that are cool to took at. The room is within a 10-15 minute walk from the nearest metro. The neighborhood is vibrant. I wish I could spend more time in the neighborhood because there were a couple of Tibetan and Afghanistan restaurants that I wanted to try.
New York is a beautiful city and staying at Chris's place will allow you to experience a piece of it. I definitely recommend staying here.
