Mary's accommodation is a perfect base for exploring DC. The walk from the flat towards the Capitol is lined with brightly painted row houses and gets you to the Mall in about 30 minutes but you could also take the (free at time of review) streetcar, which stops at 13th and H and behind Union Station.
The rooms were tidy and inviting and the bed was comfortable. After a long day, it was perfect for relaxing and recharging.
Mary was a gracious and very helpful host who offered suggestions on how best to get to her house. It was a pleasure to stay with her and I would recommend her accommodation to anyone passing through DC. Thanks Mary!
