Heading to Washington DC with my husband and kid this summer for a couple of days. I vastly, vastly prefer a hotel room that has the sitting room (w/ pull out sofa) divided from the bedroom with an actual door. Not a half-wall, not a doorless hallway, a real actual door that shuts. It's often impossible to tell from room descriptions and photos whether or not this is the case. Have you stayed in such a room in DC? If so, where?
Doesn't need to be right downtown, but does need to be on a Metro line and too far out. Doesn't need a kitchenette (though I wouldn't kick one out of bed).
