I lived at CHT at 1000 New Jersey Ave SE until just recently. It is a large building, but it is quiet. I, too, work for a federal court (and did then), and it’s incredibley easy to hop on the Navy Yard metro stop and get off at the Archives/Navy Memorial (or whatever they’re changing the name to) stop, which is just down the street from judiciary square. It would be impossible to have an easier commute unless you were literally walking/biking a few blocks from Penn Quarter, but you’ll be paying for it in rent. I would’ve stayed at CHT but I decided to buy (and I couldn’t afford the new rowhouses in that neighborhood). 2012 and 2013 will bring a lot of new retail/dining/other events to that neighborhood. The Yards park is awesome and Nats games are fun.
