We are a British family of five (including three teenagers) and stayed in the flat in July 2022.
Ryan is a very helpful and approachable host and gave us some excellent tips about where to eat locally and how to navigate the metro. The nearest metro station is a ten minute walk away and it takes about 20 minutes to get into lower Manhattan. The Clinton Hill area feels pretty safe and the locals we met were very friendly; there is also a large and well stocked supermarket less than five minutes walk away, so it's easy to self-cater. The flat itself is clean and well-equipped with a good shower and comfortable beds. The only thing that is missing for a family is a washing machine, but there wouldn't be room for one and there is a launderette at the end of the street which does service washes. We would recommend staying here if you are planning a family holiday to New York.
