Meeting Walt is like meeting an old friend you haven't seen in years. He was incredibly kind and accommodating, offering to meet us at the station to get our bags, quickly replying to inquiries, and always prepared to give suggestions on food venues or sights to see based on our interests. He keeps a binder of restaurant suggestions, menus, and maps of museums so you can easily plan your trip (or next one). The room was cozy and well prepared for all our needs and then some. He helps above and beyond what we asked. The location is in perfect walking distance to downtown DC. If you are comfortable in a city/urban environment then it's fine to walk there at night. If not, then I would suggest an uber/lyft. We had taken an uber from the apartment to the Holocaust memorial and it was only $7 which is cheaper than getting metro cards for two people. I would absolutely recommend staying with Walt if you are in need of lodgings.
