Walker's place was very centrally located in a non touristy area of Brooklyn- great for discovering the real city. Despite some small misunderstanding at check-in, Walker was able to get his neighbor to let me in.
The apartment is very comfortable and large by New York standards. The bed was also great.
If you are sensitive to loud Caribbean and hip music, be aware that at times the street outside the bedroom gets loud. Of course this has nothing to do with Walker, and adds to the local experience.
All in all, I recommend this place to travelers.
