Plusy (+) It's a perfect place to spend just one or two nights. It's cozy and have a really kind and smiling crew. It's located close to Washington DC National Station, metrobus 5A stop from the airport and all main atttractions of Washington downtown.
Minusy (-) The only issue I had was a price. It turns out that there is in Washington one other tax of 4$ per night for foreign turists not included in pricing tables of Kayak or Expedia booking services. Someone might be surprised of that (as I was).
