The neighborhood --> great place - the neighbors I met were very kind. If you forget to pack something, there are many grocery stores and corner stores open on Broadway just a block away. There are also so many good restaurants and cafes around that I sadly didn't have time for.
The space --> actually bigger than I anticipated for New York. I didn't use the back patio because Winter :( I can imagine that's very pleasant in Spring/Summer. The appliances are all pretty new and I absolutely loved relaxing in the bathtub after a long walk. The house is on a fairly busy street, but I didn't find it noisy and the bedrooms are in the rear of the house so you have no problem sleeping.

For dog owners --> I fit a large crate in one of the bedrooms, perfect fit. I didn't take my dog on the back patio cause she's used to grass, but there are lots of parks nearby with grassy area. The nearest is Thomas Boyland which is good for a quick jaunt. 15min away is Irving Square park which is not an official dog park but you'll definitely meet a lot of dog friends there and there's lots of green space. A lot of dogs are off-leash because the park is mostly fenced. All were well-behaved with friendly owners. Walk about 30min and you'll get to Maria Hernandez Dog park - again super friendly people & dogs.

The host ---> I didn't need to bother Chloe too much but she was very accommodating and responsive. I have no doubt that if I ran into any problems, she would be there to help.
