Justa's place was just as pictured and had plenty of room for up to four people. she was communicative and easy to reach - however, I will say that she was clearly uncomfortable with giving us privacy. I would say that if you are looking to be left completely alone, this is probably not the place for you. I let her know when we had guests over and that an additional person was staying over one of the nights and I got the distinct impression that she was not happy with that (though it says in her rules just to let her know).
Not mentioned in the listing is that it is about a mile away from any sort of sit down restaurant/coffee shop/bar/decent grocery store. I've stayed in Bed Stuy many times and assumed the neighborhoods would have similar offerings, which they did not. I am an every day coffee drinker, so for me it was inconvenient to be that far from any place to get coffee.
We also had issues with connecting to the WiFi (we never were able to connect via any of our phones or the amazon fire stick) so I'm not sure what happened with that.
If you are someone who doesn't mind interacting with your host, and you don't mind traveling for food, etc. then this is an affordable and spacious place to stay in Brooklyn. If you are looking for a turn-key set up and neighborhood bars to explore then I would say this is not your spot.
