We spent 7 weeks at Lisa and Christian's place. You cannot beat the location. It is within walking distance of many great restaurants and sights, and the metro stop is close by to get you anywhere you might want to go in DC. The property is in a fairly noisy area, but the bedroom is quiet. While about half of our stay was affected by the coronavirus pandemic, we were able to see many museums and other important national sights while they were still open.
Every Sunday, there's a large farmers market right around the corner that has lots of great produce, meats, eggs, baked goods, and even locally distilled liquor. We enjoyed taking advantage of it most weeks. The nearby 24-hour CVS is very convenient, and there is a Safeway nearby along with several smaller local markets.
This is a great place to stay if you want to explore the national capital area!
