Stayed at Carl's place while at a conference at the Walter E Washington convention center. My main criteria were distance from the convention center and price and this fulfilled both. The walk to the convention center is about 20 mins which was ideal for me. There is a great place called Big Bear just round the corner which is good for coffee and breakfast and I found a good running loop up around a reservoir starting right from the door (using MapMyRun). The accommodation was clean, the wifi was a bonus and the instructions for arrival worked perfectly. Carl's place is a fascinating shrine to his travels but is a work in progress and while it was fine for me some business travelers may want finished floors, air-con and a quieter street.
