This living situation is great for new NYers!
I've stayed here for over 3 months now and the other guests have always been friendly and understanding.
There are multiple options for rooms, so if the size is your issue you can check the other listings and the neighborhood of Ridgwood is pleasant, while also being close to any stores or subways you need. I'm glad I found the place when I did, the safety and security really helped while getting used to the city. :)
