I concur with the other recent reviewers. The review by Owen in July 2021 gives an excellent description of the unit, the neighborhood, and the hosts. All good!
It's a nice place in a great neighborhood. Modern, immaculately clean, and quiet. Both beds are comfortable with plenty of pillows and blankets. Plenty of towels, too.
The unit is on a quiet street just off a busier street with shops, restaurants, and bars. Columbia Heights is a short walk away. Here you'll find the Metro, as well as a supermarket, large stores (eg, Target), and more.
One reviewer mentioned slow WiFi. It was fine for us to stream videos except for a brief spell - maybe half an hour - when everything slowed to a crawl. My guess is that it was an Internet problem, not the WiFi per se.
Carlton and Guesty are great and attentive hosts. I only contacted them for a small inquiry about a kitchen appliance. They answered almost immediately - far quicker than I was expecting.
We'll definitely try to book this unit next time we're in DC!
