We stayed at Mike's place for three nights with our family of 5 (2 adults, 3 children) and it was perfect. Very easy to check-in. The parking space is very convenient to safely leave the car. We didn't have to use our car for our vacation since we walked directly from the apartment to the Capitol, museums and other attractions.
The house is clean, exactly as per the description. The kitchen is well furnished and we even used the BBQ in the backyard for one dinner.
Very easy communication with Mike. I would definitively recommend this place for anyone or any family who wants to visit Washington.
