You should stay here, because Elmar & Michelle run a great operation, are super hospitable, and have a lovely setup for travelers. You have a floor to yourself, and excellent supplies in the kitchen and bathroom.
The location is very accessible to lots of stuff in DC and accommodated me well. The location is very, very close to one of DCs best coffeeshops as well...easy walking distance. I made use of it often.
A great time with great hosts! Check it out!
