I just got back home yesterday and I miss this place so much! I felt at home being away from home and can definately recommend staying here. Kiney is a great host and will take care of you and be there if you have any questions or needs. The apartment is exactly as shown here and offers everything you need for a short or long term stay. I also felt very safe in the building and street in general.
Harlem is also a very interesting neighborhood and if you have the time I recommend doing a guided walking tour since it has so much history to offer.
Also you have quick access to the A, C, B and D metro line as well as 2 and 3 and (with a bit walking) also 4,5 and 6. So you will be well connected to the city.
I feel very lucky that I found this place and could spend my 4-week stay there. So do not hesitate :)!
