The studio apt. was as described and very clean. We felt safe and had all the basics needed for a great stay in D.C. When we first sat on the bed we worried it might be too firm - it was not. We slept great. The only thing I would change is the curtain on the sliding door. It is a bit too sheer at night. If the lights are on inside you can see in.
We were able to walk to basically everything! All the major landmarks were easily accessible. Two metro stations were very close and easy to navigate. You can get from the airport to this location easily. Don’t rent a car. Restaurants were close, some a bit pricy though, and others close a bit early so check times ahead. I would stay again.
