Michelle's place is no-frills, but in a good way. You're not going to find a better way to experience New York at this price point. Both the bunk beds are comfortable, and the room set aside for AirBnB guests is quiet, private, and good for sleeping. And although the decoration is sparse Michelle and her husband Jeff keep their place clean. They were both very nice and welcoming, but not obtrusively so, and the smart lock they've installed on the door makes it very easy for guests to get into the house without having to remember a key.
The apartment is in a part of Brooklyn quite far from more 'fashionable' parts of the city, about 45 min to an hour in most cases. But for the most part it's an easy shot on the D train, which is only a few minutes' walk away. Just bring a book for the daily trek into and out of the city and you'll be good to go. The neighborhood is definitely working class, but as far as my wife and I were concerned that was a good thing. It means there's lots of great Chinese food and pizza only a few minutes' walk away, as well as a really great Italian bakery, all at prices that are super reasonable for New York.
The only thing that we'd really call a 'complaint' was that the water pressure on the shower was quite low. But I believe my wife and I were Michelle's first guests, so hopefully that will get sorted going forward.
The bottom line here is you're getting a good base to explore New York at a good price. Once summer rolls around it'll be even better, since you're just a stone's throw from Coney Island. My wife and I both would definitely stay with Michelle again.
