We stayed for 6 nights in Hannah's apartment in Crown Heights, and had an amazing and relaxing trip. First and foremost Hannah is a wonderful host who went out of her way to ensure a smooth check-in, provide great suggestions for places to visit in the neighbourhood, and make sure we were having a great trip. She's just a ultra cool person which went a long way in making for a good experience.
The place is exactly as listed, located right next to transit and convenient for getting into Manhattan within 30 minutes (we enjoyed more than a few "Showtime" performances on the Q train on the way). It's a large place and provided ample space for 3 people. The neighbourhood is great with a variety of restaurants, or markets around for food. It's within walking distance to Prospect Park, the Brooklyn Museum, the Botanical Gardens, the Barclays's Center, and an abundance of restaurants and stores. There is an eclectic mix of cultures, people, and businesses in the area that we found perfect for our stay. Definitely fell for Brooklyn in my time there.
Amenities in the apartment are as listed. The kitchen and bathroom were clean and functional, and the bed's were comfortable with clean linens. It was nice to either wake up early to coffee or tea, which Hannah kindly provided, or to make breakfast before setting out for a long day.
The downsides are the proximity of the shuttle train next door, depending on how light a sleeper you are (note: the light sleeper in our group slept in the room nearest the train and wasn't much bothered by it). To access the larger bedroom you have to walk through the smaller room, not a bother for us, but good to be aware. We did see a few bugs in the apartment but nothing that raised alarms or made us feel uncomfortable.
Overall a great stay, and amazing host.
