We really loved staying at this AirBnB. The location is great, the room is private, with its own entrance and bathroom, spacious, clean, and comfortable. Check-in and check-out were really smooth.
The only caveat is that AirBnB lists this place as having parking, and the host suggested that parking would be relatively easy to find (which was a main reason why we booked this place specifically), but parking was sometimes very difficult to find (circling around for 40 minutes the second time we needed to find parking, and we had to move the car again early in the morning, many parking garages not allowing overnight parking, etc.). Maybe it was naiveté to presume parking in Manhattan, but I do also think it's inaccurate to list this place as having "free parking on premises" (many nearby locations do not list it).
So to summarize -- this is a fine AirBnB. The parking situation is standard for the Upper East Side of Manhattan, generally free, sometimes available but often not. If you're driving in and the "free parking on premises" caught your eye, be mindful of expectations. At the end of the day the parking situation is better than in Midtown Manhattan, and it seems you'll find something if you're sufficiently patient and flexible.
