We liked the house and we enjoyed our vacation spanning over a week. It was a good choice both in terms of comfort and price.
Jesse is a great host. He was in Europe but he was available all the time and answered our questions and concerns very quickly.
House is in Harlem. If you do not live in a big city, at night, returning home by subway, than walking, might make you having the sense of unease. The security of the school near the house looks after the building during daytime.
There are two metro stations close by. Both in a 12~15 minutes walking distance. You can have your breakfast (not bagels, but other stuff) and coffee from Lenox Coffee while walking to 2-3 subway station. We find it easy to navigate into the downtown. Also it is close to the Yankees Stadium, if you are into baseball. Central Park is in a 30 minutes walking distance.
House was clean. It is spacious and well lighted. Floors are wooden and feels nice. You have trees if you look out the window. There is a train passing by but never got disturbed by it - actually Jesse left a pair of ear plugs in case we get into trouble with the train.
Insignificant issues: The shelves by the door of the room squeaks when you walk around in the room, as it leans to the door frame. I had to put a piece of paper between them. Also, shower's glass panel keeps opening when it gets wet. You might hit it, after the shower when you are getting into or out of the bathroom. So again, I had to tighten the door by putting paper under the frame. Tap of the shower leaks, so you loose some pressure there. There is a pipe passing through the room (My guess is it is part of the heating system). It might release some pressure during the night keeping you baffled about the sound.
All in all, it is a good place to stay.
