I loved staying at Ron's place. It was all i could wish for. The room was big enough for me and my luggage, the bed was comfy, it was quiet, the AC worked just fine, the wifi as well and it even looked amazing with the stone walls. Fresh towels and linen of course. Even a home-made hot sauce as a present to take home.
Communication was great during my trip and before. Unfortunately Ron was away for the whole week i was there. But then I had the whole place for myself that way. But even with him there we wouldn't have heard it each other since the two rooms are on the opposite sides of the apt.
The location is also perfect. 5 minute walk to the subway, 5 minute walk to Time Square, 10 minute walk to Central Park etc. - Not even one hour to JFK.
I would totally recommend exploring New York City by foot by the way. For example: from the Apollo Theater in the heart of Harlem north of Central Park to the southern tip of Manhattan it's not even 3 hours.
I would definitely stay here again.
