We stayed at Karl's place in D.C. in July 2018. It was a last minute booking and there was no problems getting approved. We were a fairly large group of 4 adults, 4 children and 2 dogs. We drove in from North Carolina in 2 cars, so on-street parking was important and there was ample parking around this location, which can be a pain in D.C. (beware of the street-sweeping days though). We had to use all the bed options available, including an inflatable bed and cot. While the inflatable be had a leak, Karl replaced it the same day. We were impressed by Karl's responsiveness and attention to our needs and he made out trip a pleasant experience. I highly recommend this location for your stay in D.C.
