Would recommend with caveats. Location is superb – walkable neighborhood, easy access to restaurants and grocery, nearby parks, feels very safe. Reasonable walk to the Capitol and National Mall, but still a good 1.5 mi hike to the mall (we had great weather!). Host provides great communication and attention to detail (as an example, an excellent guidebook that calls out how to get the most of your stay).
Caveats – We spent 4 nights here. As other reviews have noted, this is not truly a two-bedroom place. To get from the main bedroom to the bathroom or family area you have to walk thru the other bedroom. It’s tight with the trundle out. The walkthrough room also has the furnace in the closet that creates noise that might bother light sleepers at night. Bathroom is relatively small and has no counter space to put your toiletries. Our stay would have been improved with some drawer space in the bedrooms so that we could get rid of the clutter of open suitcases. Kitchen is usable for light heating of leftovers or making sandwiches, but do not recommend for cooking any sort of meal.
In summary, you get a clean place, superb / responsive hosts, and a very good location for touring the best that DC has to offer. Hope these additional notes enable guests to be fully informed of what they are getting.
