Really convenient location! You can walk to central park, the upper west side, chelsea market, or take the subway closeby wherever you want.
The apartment itself is perfect as a reasonably inexpensive home base while you explore NYC. There is only one comfortable chair/no couch, so it's not really somewhere to just hang out. The TV does not work very well, nor does the WiFi, but that did not really bother me.
The kitchenette has the bare essentials you might want to make coffee or cook something small (I did not).
The bed is really comfortable. The shower is really nice and the bathroom is heated for when it gets cold in the winter. There is also a space heater that gets the job done.
The walls are not very thick so you might hear your neighbor. There is also a heating pipe next to the bed that can get a little noisy.
Management (Val) was really quick about communicating and even answered a 730 PM call on a Saturday night when I was tired and having issues getting into the building (my fault).
Overall I definitely recommend this place as long as you are OK with the caveats I listed above - I certainly would stay here again!
