Two main problems: This is NOT at the address given on AirBnB. They say they changed it for "privacy" but it feels a little like bait and switch because the home is closer to 31st and Park, which is OK, but not handy to Grand Central as the address they give makes it seem.
The second problem is that it really wasn't clean. I gave them a long list of issues, and they said it wasn't true. I guess I should have taken pictures of the food in the microwave, the dirty dishes in the dishwasher, the smelly water in the toilet bowl cleaner holder, the hair in the bathroom sink and tub, etc. But I was busy.
If the owners had been honest about the location and apologetic about the filth, I would have given them a good rating, but location matters a lot in NYC, and honesty about cleanliness is important.
