This apartment is a very good size for nyc, has a comfy bed, high ceilings, tons of storage, an empty tall closet, is very quiet (especially for the area), features a recently remodeled nice-sized bathroom (so many nyc apts have literally eye wash station-sized sinks or awkward shaping (hah) so a good bathroom is nice!), and a HUGE private patio (also an extreme rarity in the the city period but especially with an Air Bnb!).
If another review hadn't mentioned it I may not have noticed the very slight, nearby subway rumbles (and I am very sensitive to sound). When my car pulled up to the very active neighborhood, I was worried about noise but the apartment is in the back of the building, on the ground floor, and is quiet.
This is a grittier part of Manhattan but not dangerous or anything - just a little younger and wilder. There are some terrific restaurants nearby and the F/M train is right around the corner. Especially great for speedy and easy access to Brooklyn.
The hosts were very quick to respond when there was some confusion with the key pick up. Listen - Air Bnbs are almost always a bit of a hassle with keys so just go with it and know once it's figured out, you are all set (over the years of Air Bnb'ing in the city, I've had to pick up from a spot nearby and not so nearby, wait on a host, bend to the ground and figure out a code on a lockbox, in the dark, on a fence, etc). Key retrieval is one of those things we deal with because we prefer an AirBnb over a hotel, right?? It's all good.
Hosts gave recommends in the neighborhood (Ivan Ramen! get the Daikon!) and readily answered any other questions.
