Graham (and Bear) are great hosts! He easily accommodated a date and arrival time change for us. He was easy to reach when we had questions or needed anything. He also gave great recommendations for places to eat and was sure to tell us where the closest grocery and convenience stores were. He also let us use the guest parking pass for free, which made parking on the street easy and free near the apartment
The apartment itself was clean and comfortable. It had all the essentials, places to hang clothes, extra towels, and guides to things to do in the city. The location was great. It was about a 20 minute walk to the Capitol and national mall. We usually went right from that area to a bar/restaurant in that area of town and then took an Uber back to the apartment for $4-5.
Overall, it's definitely a great place to stay that we would look up again if/when we go back to DC.
