Barbara's loft is, in one word, exceptional. It is exactly as she described it, very clean, very artsy. If you are looking for a hotel room-like space with no character, her place is not for you. But if you want to come as close to the real New York experience as possible, go for the loft!
I've used Airbnb quite a bit, but I never had such a great communication with any host like I did with Barbara. She is incredible friendly and helpful and always reachable if you need anything.
The neighborhood is great as well, lots of bars and restaurants, the metro is nearby and groceries stores and easily be reached in short walking distance. Brooklyn is a great place to stay while in New York since you have an escape from the hectic world that is Manhattan but are still in the heart of this great city.
Overall, I can only recommend to stay in Barbara's loft when you visit New York.
