Had the pleasure of staying at Michael's place for 3 nights at the end of a 10 day trip. His place is a reasonable walk from Union Station and is comfortable, clean and well located. I saw Michael once when checking in and again when he offered to drive me to the airport. In between, he left a thorough contact list in the event anything came up - which it didn't. He made snacks and water available as well as numerous brochures on area places to see, transit, restaurants, etc. A good host in a good location - I recommend him for any trips you plan to DC.
