I would definitely recommend Quan and this location if you need a place to stay in NYC. Quiet neighborhood and off street parking. I arrived very late at night and she gave me detailed check in instructions with photos. The place was clean and very nice. The pull out couch was a little small so if you have 3 tall people staying that might be an issue, but it wasn't that big of a deal for me.
Also note: if you don't hear back right away when messaging in the app, she was very responsive when texting the contact number provided.
