I usually stay at hotels whenever I go to DC for business. This time, however, I decided to give Airbnb a try. The things I looked for were convenience (location wise and logistically) and comfort/cleanliness (no funky smelling sheets or towels).
Joel's basement unit is very conveniently located in central DC and just a couple blocks from 14th Street - an area filled with restaurants, bars, shops, and fitness studios (the neighborhood is also great for outdoor running). The unit is equipped with everything you'd need - towels, toiletries, full-size refrigerator, microwave, dishwater, cooking appliances, etc. I didn't take full advantage of all the amenities, but can certainly see this being great for both business and leisure travelers who prefer to not eat out every day.
Another aspect I really appreciated was Joel's communication and flexibility. I needed to have a package shipped to the place, and Joel received and held it for me. I also needed late check-in and check-out, and Joel was happy to accommodate.
Overall I had an excellent stay, and would certainly book again next time I'm in town for work.
