Edwin is a great host! Very nice and helpful. I particularly appreciated the way he was upfront about what to expect at his place. If you read his description and the reviews, you know exactly what to expect (e.g. the dog barks), and you decide for yourself if it suits your needs. We are really happy we chose his place to spend our holiday. A few tips for visitors: 1- Library of congress *****, 2- Tudor Place, 3- Spy Museum, 4- Georgetown, 5- Air & Space museum in Chantilly, 6- District Wharf, + many more!
