Doug was a great host! He gave me a lot of helpful hints about New York City. His house was very clean. Furthermore, the house is really close to Manhattan by subway. You have a lot of attraction around his stay in Brooklyn. For example you can get out in the morning to take a fresh coffee with bagel for breakfast - just a few steps to walk from Doug's house.
And one more thing - my big question was: Is Doug's neighborhood in Brooklyn really safe? YES, it is!
