We had a wonderful stay! Angelina and Mark are kind and engaged hosts: they live at the ground floor and provided us with great communication and tips.
The flat is cozy and comfortable. We enjoyed it very much, even though we were out a lot: slept well, chilled out on the sofa, made food in the very nice kitchen.
We warmly recommend a stay in Park Slope to families with small children: our 3-year old son had a great time. Many food joints and shops are at a close reach; even then, we were surprised by how quiet the block feels. Same goes for several subway stations, allowing to reach many areas of Manhattan quickly and easily.
