This is a lovely apartment. It's spacious, clean and very well-equipped, with a fully-working kitchen (unusually so for Manhattan) and a decent bathroom. The main living room is square, spacious, and comfortable; the bedroom is good, air-conditioned, with a good-size comfortable bed. The apartment is very relaxing, being on a quiet, tree-lined street and being positioned at the back of the building, overlooking a leafy courtyard. It's very silent. The wifi was good; there are plenty of channels on the TV!
The apartment is on the Upper West Side (readers of a certain age might think of it as 'Seinfeldland'). It feels like a family area, with of course some bars, restaurants and coffee shops nearby, but otherwise it's a residential and relaxed area. That said, you are 10 minutes' walk from the 86th St Metro which is on lines 1, 2,3 which take you very quickly down into Lower Manhattan; you can be in the Theatre District in 20 minutes, Greenwich Village in 30, and on the southern tip of the island in 40, maximum. So it's slightly out of the heart of NYC's cultural and nightlife but you can be there very quickly and cheaply.
Monique was an excellent host, answering all our questions very promptly and fully. The apartment is just as described in the listing. Monique sent us all the information we needed on finding the key, using the wifi, and all the rest of it a few days before.
It was a wonderful base from which to explore NYC. Strong recommend.
