We had a great stay in DC. The flat is conveniently located in proximity of the capitol (approx. 10-15 min by foot). The national mall is also accesible by foot but we used the bike sharing system that is even more convenient. The flat had a fully equipped kitchen. The bathroom is rather small but fully sufficient. The bedroom with a king-size bed was big and the pull-out sofa was also fine and could easily fit 2 persons. The only downside was that the carpet had some stains that gave us a general feeling that the flat could be cleaner...
