Unfortunately the apartment was very dirty. Ruby explained to us that before us there was a family that left the apartment with a total mess, so when we arrived the bathroom and the kitchen were very dirty and we found cockroaches.

As a host, if another family stayed before us, she had to clean the apartment before our check-in, but Ruby explained to us that she paid to her sister to clean the apartment and she didn't do it, so unfortunately the apartment was not in good conditions for us.
Ruby understand that it was a very bad and sad experience for us, because my family and I had to clean the apartment the first day we arrived, and the cockroaches was a very bad experience in our vacations, so to compensate us she offered to return part of the payment we did.
I think that even if the apartment was a total mess, it is located in a neighbourhood close to the main attractions. Transportation is good and easy, and Ruby is very kind. The apartment is exactly as the pictures show in the description.
Before to receive Ruby's explanations I was very angry and don't wanted to recommend this apartment, neither the host to anyone, but probably this just happened to us and hopefully it won't happen any more. I will wait for the refund to be done and will update this comment with any news!
Despite all, I recommend Ruby as a host, and the apartment is good if you are looking for a place to stay in Manhattan with a good price. Just be careful and confirm with her if the cleaning conditions will be good before you arrive.
