The host was incredible although I never met him. He was flexible, extremely responsive and helpful throughout the length of our stay. Could not have had a smoother experience. As for the apartment it's slightly far from the subway (10 minute walk) but conveniently located next to all the main shopping areas of the UES and easy to get to downtown in a cab via FDR. Only a couple downsides: the apartment can get pretty loud in the living room due to outside noise from the highway but the bedroom is isolated.
