Irik hosted my stay when I was visiting DC. His home is located near union station with walking distance to the Capital Building and any touristy spots(monument, WH, etc.) Even-though, it is a private room you can still expect a lot of privacy. Irik is a disciplined individual who will make sure that your room is pristine before your visit, also very sincere.
I highly recommend for you to stay here if you are visiting DC.
