First thing anyone thinking about NYC should know: Williamsburg is by far the best neighborhood to base yourself in. It's the best in NY-- safest, friendliest, best restaurants, shops, artisanal coffee, bakeries-- it's just got everything. And Adrienne's apartment is in the exact center of everything. If the best location is 5 stars, this is 7. The best location in the best city on Earth.
The apartment is nothing luxurious, the kitchen very small if you were thinking of doing a lot of cooking (which would be crazy in this neighborhood anyway)... but for the money, this is an insane bargain in NY, and very comfortable for 4 (the pull out couch is the most comfortable I have ever seen. It's like some strange alien technology-- I didn't know it was even possible for a pull out couch to be so comfortable for sleeping.
...But the best part of all is Adrienne and her incredibly kind and charming family, who live in the 2 floors above the apartment. You will feel completely at home from the moment you arrive.
