This location is just excellent, with several coffee shops, a Whole Foods market for groceries, and many restaurant choices within an easily-walkable distance.
The National Mall, with its abundance of museums and monuments, is an easy bus/Uber/Lyft ride away. And yet, the neighborhood is just that--a neighborhood, rather than a huge center of nightlife, so we found it relatively quiet and easy to sleep at night.
Nicolas was very prompt in communicating with us after we'd booked-even though we reserved at the last minute. We appreciated all his help and service and will definitely try to stay with him again next time we are in Washington, DC.
