I greatly enjoyed my stay in Wei Wei's apartment. It was a huge room with a nice view of the (primarily Asian-American) neighborhood. Wei Wei in particular is a nice, generous host who replied and aceeded to most of request in a prompt and professional manner.
The neighborhood is safe and amenities such as Target, Best Buy, Restaurants/Food and the Subway station are plenty and within walking distance. I generally had no issues coming back late at night after a day of activities.
The only issue that I had with Wei Wei's apartment would probably be ventilation - it might get quite stuffy at times and for light sleepers the air con might be a bit noisy at night.
In all, I would highly recommend Wei Wei's place to anyone seeking to visit New York City, especially when it's located in the Queen's district, enabling visitors to have a more comprehensive tour/view of the Manhattan, Brooklyn and Queens areas.
