I stayed at Lunara's apartment for nearly a week and was happy with my experience. Lunara was traveling during my stay, so I never met her, but that wasn't a problem because she was very responsive via email. Also, she had one of her downstairs neighbors serve as in-town contact, so anything I needed that couldn't be handled remotely was quickly handled by the friendly neighbor.
The location of the apartment is fantastic! It is about 1/2 a block from the subway station, in a safe-feeling area (though it is NY. so never let your guard down!), within walking distance of several nice spots, and only two stops outside of Manhattan. It is only on one subway line -- the 7-- but that line connects to many other lines within only a few stops, so getting around Manhattan via subway was not a problem.
The apartment was exactly as pictured. Nothing fancy, but everything you need at an affordable price. As one would expect of NY, the bedroom is small and there is no living room, so it is a perfect place for someone who will be out and about all day. The apartment itself is quiet because the building appeared to be mostly occupied by families, but it is located near busy streets, so there is quite a bit of traffic noise. Also, the steam radiator in the bedroom bangs and leaks steam (it was a bit humid, but my skin looked great as a result!). I brought earplugs and a white noise machine, which did the trick, so the noise didn't get in the way of a good night's sleep. There is an incense fragrance in the apartment -- this did not bother me (I like it), but it might bother someone who has sensitivity to fragrance. The key to the apartment requires a bit of maneuvering to work, so make sure to ask Lunara or her neighbor to show you the trick-- this caused me quite a bit of anxiety at first (I didn't want to be locked out late at night), but I quickly got the hang of it and I never had a problem getting into the apartment.
