Donna's place is wonderful. She was very responsive by message (I never saw her in person) and the whole experience was flawless. All the doors have keypads for automated entry, which makes check-in and coming and going easy. The place was clean and her instructions/house rules (which include putting your own sheets into the washer at the end of your stay) were clear and reasonable. The location is very residential and quiet and a mere 10 minute walk from the conference center, about a 30 minute walk from the Capital/National Mall, and about a 20 minute walk from Union Station. The bathroom, kitchen, and living room (which are shared with other guests) were all clean. Donna was kind enough to let me leave my bags in the living room before check-in and after check-out.
