I had a great stay at Yolanda's house! All the communication with her, before and during our stay, was fast and easy.
It is a bit far from Manhattan (about 40 minutes to the Lower East Side on the J train | the house is 5 minutes from the station) but there are several shops and restaurants nearby. I was in New York for an art exhibition and needed a place to sleep and to shower on a budget and I've received even more: her kitchen has all the appliances you might need to have a good breakfast or late night snack, she provided towels and sheets, and the wifi was really good.
Just be aware of the services on the subway (nights and weekends) to better plan your trip.
I would stay there again in the future.
