Mona's place is great for a trip to NYC! I stayed there with my mom for her birthday, and we found it cozy and clean, and VERY close to the subway (which was so helpful!)
This is neither a positive nor a negative, but potentially relevant! The apartment is quite small, and there were a number of scented products that left the place with a quite noticeable (but not unpleasant) scent. If you are scent sensitive, that would perhaps be useful to know! We found that opening a window and moving a few of the scented products to a closed room (which Mona was very understanding of) addressed it.
Mona herself was so lovely--really gracious and available, and very helpful when I had a bit of a boneheaded moment trying to open the door to the apartment. Would highly recommend staying here!
