We had a great weekend trip to DC. Mark's place is in a great location and the unit itself was perfect. The owner did a great job with the set up and was responsive to all our needs. Check in/out was simple and quick. There are great restaurants and bars nearby and Uber's are readily available to get around the city for cheap. If your a seafood lover be sure to make reservations at Fiola Mare truly a gem in the Georgetown waterfront.
The only issue we had was the wifi and we had to restart the router a couple times and still was super slow that we ended up not using it. But overall highly recommended unit, thanks to our host Mark!
