Great place in a great location. Near convenient subway lines and buses, close to Prospect Park and Barclay's center. Many great food options within a few blocks. Host was very responsive to inquiries.
It's a garden level apartment, so there's not a ton of light, which has its pros and cons: The beds are super comfy and you can sort of lose track of time and accidentally sleep til noon because the light in the apartment doesn't really change. But it's also pretty quiet for being on a fairly busy street.
Stayed there with spouse and two kids, no issues, was definitely roomy enough. If you're looking for a Park Slope stay, would definitely recommend.
