Chris is responded very kindly and timely manner when I approached him with questions. He welcomed us when we arrived and show us his house thoroughly. Everything might needed by a guest is fully equipped, and he is willing to provide more than you may asked(e.g. freshly ground coffee in the kitchen cabinet). I feel very welcomed when I arrived and feel like it's my friend's house while I was staying. It was slightly further than I expected from the Walter E. Washington Convention Center, but the metro station was near by, and you can always using the rental bike with low fee.
