There is only one hotel in Park Slope, so I rely on AirBnB often. Nina was a great host. The apt is small but immaculate. The full kitchen is well-equipped.The AC was essential this hot week. I loved the convenient location within 6 blocks of the local hospital, a subway station, and lots of delicious restaurants.
One caveat: the bathroom is tiny. This could be a concern for elderly travelers. It has a small clawfoot tub with a water saver showerhead. I'm over 70, tall & fit, but climbing in & out of the tub safely to shower was difficult for me. My husband would not have been able to manage it.
