Anna's apartment is good if you're looking for a convenient Brooklyn location, with easy access to lower Manhattan. It's Williamsburg, so be prepared for noise, trash, smells, etc...but also proximity to trendy food and drinks.
If you're going to be spending time in the place, I might look elsewhere as it's tight...but you're in New York so that's par for the course.
Another note of caution - if planning on working here, double-check with Anna to make sure there's a desk. The photos depicted one, however, there wasn't one when we arrived.
