I am very pleased with my stay at Sonder Callisto. Very good relation between price and quality. The studio was clean, very well-equipped, free wi-fi. No problems with check-in (access codes are required to enter). I don't have a car, so I used public transport. Sonder is conveniently located for people like me. Stops of several bus lines are within 1-2 minutes walk. Two subway stations (Navy Yard / Ballpark and Eastern Market) are approximately 3/4 mile away. You can get to them by bus. There are plenty of restaurants and cafes on 8th Street. Grocery shopping can be done nearby in Harris Teeter until late in the evening.
