Karl is incredibly friendly, generous, and responsive. He has a washer and dryer that he allows guests to use, which I thought was awesome. The neighborhood is gorgeous and peaceful, making for great walks, but it's also close enough to the city that it's the best of both worlds. Even though you are living in a private basement unit that is attached to a house, it feels secluded. It was tremendous value overall. I'd recommend to anyone staying in the DC area
