I went to New York on holidays, and found this airbnb on really short notice, so I was glad it worked out that quickly and that easily.
Wayne is a super accomodating host, although I didn't see him much as he he also super busy. However, his team helped me out, whenever I had a question.
The area of this room is a beautiful, family-friendly area in Harlem, about 4 blocks from the next subway, which was very handy. Safety concerns were completely out of place, even at night I never saw any sketchy people around.
The semi-private room is a bed in the general living room that is hidden behind screens in the corner. I didn't find it too loud at all to sleep there, if anything, it was the nearby staircase into the living room that made some noise. I didn't mind that, though, as it was always only early evening and morning, when there was some noise (and obviously I didn't come to NYC to sleep in till noon).
The house itself is a gorgious brick house with lots of floors and rooms, the kitchen is huge (and you can use that, too) and it even has a backyard.
All in all I found it a pleasant stay at Wayne's place, the price is very reasonable for New York standards (don't forget you're in Manhattan!). I can absolutely recommend it!
