The good:
Location - pretty close to the subway, so great connectivity to NYC and beyond
Adorable cat - Gigi, their cat was adorable. 5 stars for her!
AC - we visited on a very hot, humid weekend. The effective and strong AC was a life saver!
Kitchen: The kitchen was well stocked and we appreciate the fact that they were ok for the guests to use kitchen stuff.
The bad:
Cat litter/poop smell: The living area smelt of cat litter/poop for the whole of our stay. And there was litter on the floor. As cat parents ourselves, we didn't mind having the cat around, infact we enjoyed it. But having to spend 4 days smelling (rather trying not to) unchanged smelly cat litter was painful.
Cleanliness: Dry splotch on the kitchen counter, used underwear hanging in the master bathroom, stained (looked like blood) pillow cover in MB, untidy backyard - nowhere as clean as the photos suggested. On the whole place was unclean and untidy, pretty disappointing.
This is my first not so good experience with Airbnb, in our 8+ experiences so far.
