We stayed a little over a week at Jasmin's place. We found it to be just as decribed and a great location for exploring the National mall and Smithsonian. We walked everywhere (we like to walk). But also walked to East Market for Saturday farmers market, and all of H street and to Union Square for lots of food options. REI is nearby, Whole Foods and Giant for groceries, and CVS pharmacy.
We definitely would stay here again and recommend it to others.
