Our stay was great! The hosts were very thoughtful and left bottled water, sweet treats and Metro cards for us. We met Gonzalo when we arrived and he gave us directions to the closest Metro stations and restaurants.
The basement was spotless, neat and gave us plenty of room. It's also in a very central location. We loved that there were several restaurants within a 5 minute walk, as well as a CVS and Safeway. I think we stopped at the Safeway at least once a day! :)
The neighborhood felt very safe. There were always folks out and about with their families and walking their dogs.
We'd absolutely recommend and stay again. It's much more private and spacious than a hotel and gives you a feel for what it'd be like to live in DC.
