We stayed 5 nights at Will's place in Brooklyn. We enjoyed our stay. The appartment is well appointed, spacious and there is all you need for a short stay. Clean.
Like everywhere in NY it can be loud, a lot less than in Manhattan though.
It is easy to get to Manhattan on the train (Q train 10mns walk from the appartment) and there are lots of restaurants and deli / grocery shopping opps close by.
We, unfortunately, realised what the neighborhood has to offer only our last day. Do take the time to see Brooklyn: Park Slope and Boerrum Hills are great.
