John-Michael has a great place located roughly a mile off the mall. It's close to Union Station and Capital Bikeshare, but also within walking distance of many of the attractions.
The house was VERY clean (even up to my near-OCD standards), and John-Michael added a lot of extra touches, like a fan and heater in the closet, extra blankets, bath robes, a bottle of wine, and some D.C. souvenirs to take with us.
Check-in (and out) was a breeze, with directions sent a few days ahead of time. We walked in to find an envelope of other instructions on the foyer table, and even more detailed information in a stack of papers in our room-- answering just about any question we could've come up with!
Everything was clearly labeled and easy to find. John-Michael is obviously a very thorough, meticulous guy who knows how to make his guests feel right at home. Would definitely recommend!
