We enjoyed our stay in Rafael's and Laura's Brooklyn flat. We communicated with Laura, who was both very kind and helpful. Check-in (and -out) was super easy - Laura even sent a little video that explained.
The flat is a five-ten minutes’ walk away from a couple of metro stations, so getting to Manhattan is easy. There are several restaurants and small shops in the vicinity. The flat was spotlessly clean, the wifi worked fine and our hosts had left candy and other small amenities.
With eight beds (single or double) and a sofa bed, the flat will fit ten. While there is a small kitchen, there is not really anywhere more than a couple of people can sit and eat. So don't count on eating in if you're many. There are also other, small issues that detract from the overall score (I’ve made a few suggestions to the host).
Overall, however, if you’re a group visiting New York and need a spacious flat where you’ll essentially just sleep (like we did), then this is an excellent choice.
