This was my very first Airbnb experience, so I have nothing to judge this against. However, the two big points are:
1) that I stayed one night at the end of January and the room was sweltering hot and barely cooled down in the 12 hours I was there. The heating unit was a radiator, which I've never had experience with. The Airbnb app delayed my messages to the host or something because she didn't see them until much later, after which she did adjust the heating.
And 2) The room is in an apartment building in Washington Heights. Having never been to New York, it was a personal lack of knowledge/experience that meant I didn't know distances between things or where all the action is or which are touristy places. But three Uber drivers and several personal friends made me feel really uncomfortable about having to stay there.
However, neither of these things are really in the host's control. Its more of Airbnb's side on the location and app shortcomings. (And some people might appreciate an 85° room when it's 40 outside)
On the plus side, 1) everything seemed clean, freshly laundered, etc., 2) this host allows you to leave your luggage with her before check-in, which was great and 90% of the reason I chose her, 3) it sounded like she cleaned the bathroom between guests taking showers, 4) there were snacks and drinks available in the personal bedroom, and I believe? the kitchen was there for guests to use freely, 5) the bed is at a height easily accessible to children and the elderly, and 6) the host seemed friendly and ready to accommodate and answer questions.
