My husband, 3-year old and I had a wonderful stay at Stephanie and Ryan's place in Crown Heights. Stephanie and Ryan were great hosts and the apartment was lovely. It was very comfortable and quiet and was the perfect amount of space for the three of us. Although we didn't notice too much noise, there were sound machines in the bedrooms, which was a nice touch. The beds were also very comfortable. The neighborhood is a perfect location for exploring NYC. Crown Heights is super fun with lots to explore and many great restaurants, and it felt very safe. The location is also very convenient for visiting other neighborhoods in Brooklyn and getting to Manhattan easily with the subway just two blocks away.
The only other things I'd share if you are considering staying here: the apartment is a walk-up with two flights of stairs, but it felt very manageable. Also, the rooms didn't get that dark at night, so if you are someone who needs pitch black to sleep, you may want to bring a sleep mask
