TL;DR, I was there for a month and if you just need a comfortable, clean place to crash that's convenient to everything, you'll be totally happy here (especially if say, a corporation is footing the bill, it's pricey for what it is). But know that it's not a cute block/neighborhood and there are some minor annoyances with living in a place that nobody really lives in and has more of a corporate apt feel.
Now for more details. The best thing about the place is location, it's really close to everything in the theatre district (I saw so many shows) and very well connected (easy access to Port Authority and Times Square subway stations which can get you everywhere.) Also, it's on a quieter block, so despite being pretty close to the action, it wasn't a crazy busy or loud block (except for one night, see below). Other great things: a super comfortable and stylish bed, some very cute additions like scented candles, nice lamps and bedside tables, had a bit of a boutique hotel feel. Nice blackout shades to keep the street light out.
The cons: the building isn't that nice, and you're not far from where the garbage is stored indoors so before garbage day, it can smell bad in the hall. It's a pretty mixed area, with a fair amount of random people about, though only one night where those people camped out outside the building and shouting until the late hours. The setup in the kitchen and bathroom is pretty barebones, what you'd expect from say a corporate apartment, where nobody actually lives there and uses the stuff, so I don't recommend extensive cooking. For example, the range needs to be lit every time you turn it on, the mugs are super small and the plates are awkwardly large and heavy (I just bought my own plate to use). Similar annoyances in the bathroom like a shower curtain liner that despite magnets drifted toward me, taking up the whole shower space and clinging to me every shower. For the first ten days of my stay, there was no chair to be used with the desk/table area, so I had to hobble together a way to zoom into meetings and do work, but once I got a stool, and then a chair, it became a lot more comfortable to get work done and eat meals there (and hopefully they'll still be there so the next person won't have to worry about this).
Overall, management is pretty responsive, and any urgent needs were managed right away, like a person came immediately to fix plumbing issues. Since it was a new airbnb, I did give them more feedback on stuff that would be useful, like a bath mat for the bathroom and a chair for the table, and those trickled in much more slowly, with spotty timing and coordination.
But of course, if you're going to spend your month here being out and about and don't need to cook, eat, or work at home, then you'll be very happy here!
