My wife and I had a very pleasant stay at Hillary's Airbnb. For us, the location was the most important aspect in our choice as our son and family live just around the corner on 13th St, so this unit easily met that requirement.
Since our trip to DC was to visit family and "act like tourists," we only spent a couple of hours in the unit in the morning and a few in the late evening, so we didn't do any cooking other than fixing a light breakfast. However, the kitchen was equipped well enough that you could cook a meal... but why would you want to when there are great restaurants nearby! Try the Roaming Rooster for amazing chicken.
If you have a rental car, Hillary will enter your vehicle info into a website and then you can park anywhere in Zone 1, which was a plus, and when we weren't using the car, we used Metro via the U St station.
Since this is a basement unit, you will hear some activity above the unit, but we got used to it and didn't find it to be objectionable. Enjoy!
