If you're visiting New York, staying on Staten Island makes the most sense. A free 25min ferry ride past Statue of Liberty every morning and evening is a relaxing way to prepare the mind for the rigours of dealing with the NY bustle.
Jingyi's place offers a great, quiet location (30min walk or 15min bus to ferry terminal), great value (just see what you get for this price in New Jersey or Brooklyn) and comfort. It is extremely clean and fresh, with a five star private bathroom and super comfy bed. Any drawbacks? Slightly impersonal and no private kitchen facility or utensils in the common area, but these are small niggles considering the price. She may already have fixed these issues.
Overall, I would heartily recommend Jingyi's place and Staten Island
