We had a lovely stay at Brian and Rachel's apartment. First of all, the location is unbeatable--a quiet street in picturesque Park Slope, an easy walk to Prospect Park and plenty of shops and restaurants. The subway was about an 8 minute walk away. Second, the apartment was very clean and comfortable, and great for our family with two young children. There are several thoughtful touches that made the experience stand out; including radiant floor heating, muffins to welcome us when we arrived, coffee and basic foodstuffs provided, a lovely large bathtub, and toys and a pack and play for our kids. Finally, Rachel and Brian were easy to communicate with and it was clear they wanted to make our stay as positive an experience as possible.
A couple of things to note, especially if you are challenging with young children: There is a flight of stairs within the apartment that goes up to the one above (we blocked this off so our toddler wouldn't climb up). And, there are small windows from the bedrooms to the hallway that could let light in (important if your kids need darkness to sleep). We kept the hallway light off and it was fine. There was no stove/oven, but there was essentially everything else, and we did not miss it. None of this detracted from the otherwise great experience we had--would definitely stay here again!
