We had a great stay here! Erik is a great host and it's a perfect location for visiting DC. Super walkable and safe area near everything you could want (coffee shops, Safeway, great restaurants, etc). We were able to street park for our entire stay (8 days) with no trouble, but we did visit before peak tourist season. You'll definitely get your steps in with this location but there are numerous public transit options (Spin, Bird, Lime, BikeShare, etc) that are cheap and easily accessible.
The unit itself has a few spots that are a tight fit (narrow steps to the front door, corner between the bed and laundry) but was no trouble for us college kids. Small touches like the Brita and shower head made the stay that much better!
Highly recommend breakfast at Farmers and Distillers and the International Spy Museum!
