I stayed at Tony's apartment with a friend in order to explore DC and to interview at a local hospital. Tony's apartment was great. It was a private basement apartment only two blocks from the metro. It was clean and secure with very nice decorations and modern appliances which included a small kitchenette with stove top, sink, fridge, and even a washing machine. We had everything we needed and he even provided guest street parking passes and two chocolates on the desk for our arrival.
We accidentally showed up too early for check-in but Tony was very understanding and fixed the apartment up quickly for us. I recommend this Airbnb highly for anyone visiting DC.
