Yuan was a great host, she answered all questions promptly and gave very clear instructions. During the stay, she was very friendly. The fact that she lives in the apartment herself should be noted as a plus because I think every guest takes better care of the apartment in such a case.
The room was exactly as described and shown in the pictures and included all essentials, even an own mirror.
One can quickly reach two metro lines from the apartment to go downtown. Moreover, many grocery stores can be found close by.
From an American perspective, the room was clean. (From a European perspective, it was not completely clean. I could still find debris. But that is due to cleaning equipment in the US. Thus, I was already used to this because of the way my US apartment was let to me and cannot complain about it.) The bathroom was very old and the shower was not in a very good shape, but this is not Yuan's fault. That is probably how it is like in NYC.
