Ally was a very kind host. The room is spacious, the bed is amazingly comfy, and the neighborhood is safe. The apartment is super close to the J line (5 min walk) which gets you access to almost every other train. Keep in mind it's approximately 40 minutes to lower Manhattan. This didn't matter to me as much because there's tons to see in Brooklyn and that is where I spent most of my time.
The apartment is on the fourth floor. Be prepared for stairs. Great for calves and digestion :-) Not so good if you have bad knees.
