I chose this spot because of its location and it did not disappoint. Easy walk to the subway, good food, Brooklyn Museum, and Prospect Park. It was comfortable and convenient. I was totally fine with the 4th floor walk up, but make sure that you are really comfortable bringing your suitcase up and down all those stairs. Folks in the building were friendly.
When I had a little Internet problem, Rosalynn responded quickly. There were a few things in the home I couldn't figure out (how to turn on the living room ceiling fan and how to keep the bedroom fan on without lights), but they weren't a big deal and I'm sure Rosalynn would have responded quickly if I had asked her about it. The A/C worked great, especially considering the August heat and humidity.
One thing to note is that it appears that the host lives there, and just stays elsewhere when it gets rented. I like that because it means I'm helping someone with their rent rather than renting an airbnb-only space which takes away valuable housing in a gentrifying community. The only downside is that there isn't much space for your own things. Probably not a big deal for short stays, but possibly an inconvenience for longer visits. There wasn't space for me to unpack my suitcase and the fridge/freezer are half filled. I also felt nervous touching/disturbing any of her things (the host didn't give me any indication that she cared, it was my own hang up). I guess I'm just trying to say that it was a good reminder that I'm renting someone's apartment, not a hotel room.
I enjoyed it overall and would totally consider coming back next time I'm in town.
